    Chapter 1. INTRODUCTION Figure 1. CDM-570L 1.1 Introduction The CDM-570L (Figure 1-1, shown above) is an L-band Satellite Modem, intended for closed network applications. • It offers variable data rates from 2.4 kbps to 5 Mbps, in BPSK, QPSK, Offset QPSK, 8-PSK, and 16-QAM modes.

  • Page 25: Edmac

    1.1.2 AUPC An important feature in the CDM-570L is the addition of Automatic Uplink Power Control (AUPC). This feature enables the modem to automatically adjust its output power to maintain the Eb/No of the remote end of the satellite link constant. This provides protection against rain fading, a particularly severe problem with Ku-band links.

  • Page 26: Verification

    1.1.5 Data Interfaces The CDM-570L includes, as standard, a universal data interface that eliminates the need to exchange interface cards for different applications. The interfaces offered include: • EIA-422 (EIA530) DCE (at rates up to 5 Mbps) •...

  • Page 27: Fast Accessible Options

    1.3.2 FAST System Theory FAST is an enhancement feature available in Comtech EF Data products, enabling on- location upgrade of the operating feature set without removing a modem from the setup. When service requirements change, the operator can upgrade the topology of the modem to meet those requirements within minutes after confirmation by Comtech EF Data.

    At the time of writing, Comtech EF Data is planning to release a new codec, which is a combination of Turbo Product Coding and Low Density Parity Check (LDPC) coding.

  • Page 109: Viterbi

    (i.e., does not fail rapidly below a certain value of Eb/No). Note that in BPSK mode, the CDM-570L 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 110: Table 12. Concatenated Rs Coding Summary

    Viterbi decoder is spread out over a number of interleaving frames, so errors entering the RS decoder do not exceed its capacity to correct those errors. In the case of the CDM-570L, two different RS code rates are used, according to the mode of operation.

    – the natural consequences of the higher-order modulation. The CDM-570L implements a Closed Network version of Rate 2/3 8-PSK/TCM/RS, using either the 220, 200 or 200,180 Reed-Solomon outer codes. Although not compatible, it provides identical performance to the Open Network IESS-310 standard.

    2 – 3 dB below the Viterbi/R-S or TCM cases With this release of the CDM-570L, Comtech EF Data now provides the best Forward Error Correction technology currently available, offering a very broad range of TPC code rates, combined with the entire range of modulation types, from BPSK to 16-QAM.

  • Page 113: 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.

  • Page 115: Uncoded Operation (No Fec)

    There are occasions when a user may wish to operate a satellite link with no forward error correction of any kind. For this reason, the CDM-570L 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 116: Cdm-570L Satellite Modem With Ip Module Revision

    However, if uncoded operation is used, there is no way to recognize a data false lock. The demodulator will indicate that it is correctly locked, but the data out will not be correct. This problem has been almost entirely eliminated in the CDM-570L with the fast acquisition algorithm which includes Fast Fourier Transform (FFT) techniques. However,...
