Page 279: Viterbi
Chapter 7. FORWARD ERROR CORRECTION OPTIONS Introduction As standard, the CDM-625 Advanced Satellite Modem is equipped with four Forward Error Correction encoders/decoders – Viterbi, Sequential, concatenated Reed-Solomon and Trellis (which is available with the 8-PSK FAST option). The constraint lengths and encoding polynomials are not only Open Network compatible, but are also Closed Network compatible with the vast majority of existing modems from other manufacturers.
Page 280: Chapter 7. Forward Error Correction Options
(i.e., does not fail rapidly below a certain value of Eb/No). Note that, in BPSK mode, the CDM-625 only permits a coding rate of 1/2. Because the method of convolutional coding used with Viterbi, the encoder does not preserve the original data intact, and is called non-systematic.
Page 281: Reed-Solomon Outer Codec
R-S decoder do not exceed its capacity to correct those errors. In the case of the CDM-625, different R-S code rates are used according to the mode of operation: Closed Network Modes and Open Network Modes.
Page 282: Open Network Modes
This may be due to the carrier-recovery circuits, or the synchronization threshold of the primary FEC device, or both. In the CDM-625, and Rate 1/2 operation, this threshold is around 4 dB Eb/No. Below this value, operation is not possible, but above this value, the error performance of the concatenated R-S system produces exceptionally low error rates for a very small increase in Eb/No.
Page 283: Turbo Product Codec (Hardware Option)
– the natural consequences of the higher-order modulation. The CDM-625 fully implements the IESS-310 specification at data rates up to 20 Mbps. In accordance with the specification, the R-S outer code can be disabled. Performance curves for both cases are shown in the following figures.

Page 285: Ldpc Versus Tpc
Patent, granted in 2007. Comtech EF Data chose the CDM-600 platform as the first satellite modem in which to implement both LDPC and 8-QAM, and the CDM-625 includes a newer technology version of the original design. 7.7.2 LDPC versus TPC Is LDPC better than TPC? The answer must be ‘sometimes, but not always’, and there are issues...
Page 286: Table 7-5. Available Tpc/ Ldpc Modes
1/2 to 0.95, both an LDPC and a TPC codec need to be offered. In order to meet this requirement, Comtech EF Data has developed a combination LDPC/TPC Codec module that can be added to the CDM-625 Modem. Table 7-5 outlines the operating modes provided by this module.
Page 287 * The occupied bandwidth is defined at the width of the transmitted spectrum taken at the –10 dB points on t he plot of power spectral density. This equates to 1.19 x symbol rate for the CDM-625 transmit filtering. ** Included for comparative purposes...
Page 288: End-To-End Processing Delay
In many cases, FEC methods that provide increased coding gain do so at the expense of increased processing delay. However, with TPC, this increase in delay is very modest. Table 7-7 shows, for the CDM-625, the processing delays for the major FEC types, including the three TPC modes.

Note that SNR is used in place of Eb/No – a convention for comparing ACM ModCods. SNR is defined as Eb/No + 10log(Spectral Efficiency).

Page 292: Uncoded Operation (No Fec)
There are occasions where a user may wish to operate a satellite link with no forward error correction of any kind. For this reason, the CDM-625 offers this uncoded mode for three modulation types – BPSK, QPSK, and OQPSK. However, the user should be aware of some of the implications of using this approach.
Page 293 CDM-625 Advanced Satellite Modem Revision 13 Forward Error Correction Options MN-CDM625 The second problem inherent in PSK demodulators is that of ‘data false locking’. In order to accomplish the task of carrier recovery, the demodulator must use a non-linear process. A second-order non-linearity is used for BPSK, and a fourth-order non-linearity is used for QPSK.

Page 317: Introduction
Chapter 8. AUTOMATIC UPLINK POWER CONTROL (AUPC) Introduction You MUST obtain permission from the Satellite Operator to use this feature. Improper use of this feature could result in a transmitting terminal seriously exceeding its allocated flux density on the Operator’s satellite. This could produce interference to other carriers, and could cause transponder saturation problems.
Page 318: Setting Aupc Parameters
CDM-625 Advanced Satellite Modem Revision 13 Automatic Uplink Power Control (AUPC) MN-CDM625 Setting AUPC Parameters The important consideration is that EDMAC framing should be enabled. 1) Use the SELECT: Configuration  Mode menu to first select EDMAC framing. You may select EDMAC as IDLE, or define the unit as an EDMAC Master or Slave.

CDM-625 Advanced Satellite Modem Revision 13 Automatic Uplink Power Control (AUPC) MN-CDM625 8.2.3 Alarm This defines modem behavior if the maximum power limit is reached while under AUPC control. The two choices are: • NONE (no action) – default setting.
Page 320: Monitoring
CDM-625 Advanced Satellite Modem Revision 13 Automatic Uplink Power Control (AUPC) MN-CDM625 Monitoring Comtech F Data strongly cautions against the use of large values of permitted power level increase under AUPC control. Users should consider using the absolute minimum range necessary to improve rain-fade margin.
Page 321: Transmit Clocking
DTE also returns the clock (Terminal Timing, or TT) – the modem can accept it if it is present, but uses ST if it is not. At rates above 2 Mbps, Comtech EF Data highly recommends that you return TT to ensure the correct clock/data relationship.
Page 322: Chapter 9. Clock Modes And Drop And Insert (D&I)
Sect. 9.2.2 in that, in this mode, the signal appearing on TT is used to provide the timing reference for the transmit side of the CDM-625. However, in this mode the ST pins on the interface are active and provide a copy of the RX Satellite clock (i.e., the clock from the demodulator, prior to the buffer).

CDM-625 Advanced Satellite Modem Revision 13 Clock Modes and Drop and Insert (D&I) MN-CDM625 X.21 Notes The central feature of X.21 is that the DCE supplies the clock for both directions. Therefore, the first requirement is that TX and RX data rates are the same. Because the DCE doesn’t get an input clock moving in the same direction as its input data, the several nanoseconds of delay through long cables and the modem’s data transceivers can cause the clock phase to change...

CDM-625 Advanced Satellite Modem Revision 13 Clock Modes and Drop and Insert (D&I) MN-CDM625 RX Buffer Clock = Insert (D&I only) The E1 or T1 clock recovery from the IDI G.703 port serves as the RX Buffer reference. In addition, the recovered data is the E1/T1 input to the Insert Mux. If the RX G.703 recovery circuit detects no activity at IDI input, or cannot detect the expected frame format, Buffer Clock = RX Satellite will be chosen as a fall-back.

G.703 synchronizing signal. However, with the G.703 clock extension mode this may become unnecessary, as the CDM-625 – operating at either end of the link, where the local modem has access to a high-stability G.703 signal – can provide an almost perfect copy of this signal at the distant end.
Page 332: Clock Extension Mode 2
CDM-625 Advanced Satellite Modem Revision 13 Clock Modes and Drop and Insert (D&I) MN-CDM625 emphasized that the synthesis is exact. The net result is that the E1 or T1 timing signal used at the local end is reproduced at the distant end, regardless of the link data rate.

Page 338: Application Requirements
• Link must be full duplex. • A CDM-625 must be used at the end of the link where the cancellation needs to take place. • The transponder is operated as Loopback. That is, each end of the link must be able to see a copy of its own signal in the return (downlink) path from the satellite.
Page 339: Figure 10-1. Conceptual Block Diagram
2) Frequency offset and drift: Common sources are satellite Doppler shift, up and down converter frequency uncertainties, and other drift associated with the electronics in the CDM-625 itself. The CnC module tracks and compensates for this frequency offset and drift.
Page 340: Operational Recommendations
CDM-625 Advanced Satellite Modem Revision 13 DoubleTalk Carrier-in-Carrier Option MN-CDM625 4) Link Asymmetries: Various asymmetries in the forward and return link can produce differences in the relative power of the two received signal components. These can be both deterministic (static) or random (and time varying). An example of the former would be the differences resulting from antenna size/gain variations between the two ends of the link.
Page 341: System Functionality And Operational Considerations
The transponder downlinks the composite signal containing both carriers on the same band to the CDM-625 which then translates the signal to near baseband where it can be filtered (decimated) and then processed as a complex envelope signal. The CDM-625 then suppresses the version of the near end carrier on the downlink side and then passes the desired carrier to the demodulator for normal processing.
Page 342: Figure 10-3. Same Link Using Cdm-625 And Doubletalk Carrier-In-Carrier
Figure 10-3. Same Link Using CDM-625 and DoubleTalk Carrier-in-Carrier Figure 10-4. Duplex Link Optimization The CDM-625 CnC module operates on the near-zero signal before the demodulator, and is waveform agnostic. This means that no prior knowledge of the underlying modulation, FEC, or any other waveform specific parameter is required in order to perform the signal suppression operation.
Page 343: Doubletalk Carrier-In-Carrier Cancellation Process
CDM-625 Advanced Satellite Modem Revision 13 DoubleTalk Carrier-in-Carrier Option MN-CDM625 must be kept in mind when troubleshooting a system that utilizes the DoubleTalk Carrier-in- Carrier technique for signal suppression. One possible way to mitigate false peaks is to narrow the correlation window. For example, if the delay is known to be around 240ms, set the minimum search delay to 230ms and the maximum search delay to 250ms.

• The value of Max ModCod may be limited by other FAST codes installed in the CDM-625. For example, suppose the 4100 ksps FAST option is installed, and the symbol rate set to 4100 ksps, the theoretical maximum data rate would be 14 Mbps at ModCod 11. However, if CnC is being used with a 10 Mbps FAST limit, then ACM Max ModCod will be limited to ModCod 7, or 9.6 Mbps.
