  • Page 299: What Is Doubletalk Carrier-In-Carrier?

    Comtech EF Data’s DoubleTalk Carrier-in-Carrier serves to resolve this issue. 15.2 What is DoubleTalk Carrier-in-Carrier? The SLM-5650A’s DoubleTalk Carrier-in-Carrier (CnC) option uses a patented signal processing algorithm developed by Raytheon Applied Signal Technology that allows both the forward and reverse carriers of a full duplex link to share the same segment of transponder bandwidth, using patented “Adaptive Cancellation.”...

  • Page 300: Application Requirements

    • Link must be full duplex. • An SLM-5650A 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 301: Figure 155-1. 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 SLM-5650A itself. The CnC module tracks and compensates for this frequency offset and drift.

  • Page 302: Operational Recommendations

    SLM5650A_CDM625 Satellite Modem Revision 8 DoubleTalk Carrier-in-Carrier Option MN-SLM5650A In a number of ways, CnC carriers behave similar to conventional carriers in satellite links. They are both exposed to adjacent carriers, cross-polarization and rain fade, and exhibit impairments when any of these become too great. In addition, CnC operates in an environment where: Carriers intentionally occupy the same spectral slot;...

  • Page 303: System Functionality And Operational Considerations

    The transponder downlinks the composite signal containing both carriers on the same band to the SLM-5650A, which then translates the signal to near-baseband where it can be filtered (decimated) and then processed as a complex envelope signal. The SLM-5650A 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.

    Figure 15-3. Same Link Using SLM-5650A and DoubleTalk Carrier-in-Carrier Figure 15-4. Duplex Link Optimization The SLM-5650A 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.

    SLM5650A_CDM625 Satellite Modem Revision 8 DoubleTalk Carrier-in-Carrier Option MN-SLM5650A be kept in mind when troubleshooting a system that uses the CnC 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.

  • Page 395: D.1 Forward Error Correction Options

    Appendix D. MODEM OPTIONS Forward Error Correction Options As standard, the SLM-5650A Satellite Modem is equipped with three Forward Error Correction (FEC) encoders/decoders: Viterbi, concatenated Reed-Solomon, and Trellis (available with the 8PSK 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 396: D.2 Viterbi

    A major advantage of the Viterbi decoding method is that the performance is independent of data rate, and does not display a pronounced threshold effect (i.e., does not fail rapidly below a certain value of Eb/No). Note that in BPSK mode, the SLM-5650A permits code rates of 1/2, 3/4, and 7/8.

  • Page 397: D.3 Reed-Solomon Outer Codec

    SLM-5650A Satellite Modem Revision 8 Appendix D MN-SLM5650A Reed-Solomon Outer Codec The concatenation of an outer Reed-Solomon (R-S) Codec with a Viterbi decoder first became popular in the early 1990s as a means to permit significant improvements in error performance without significant bandwidth expansion.

  • Page 398: D.4 Closed Network Modes

    This may be due to the carrier-recovery circuits, or the synchronization threshold of the primary FEC device, or both. In the SLM-5650A, 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 399: D.5 Trellis Coding (Fast Option)

    – the natural consequences of the higher- order modulation. The SLM-5650A fully implements the IESS-310 specification at data rates up to 51.84 Mbps. In accordance with the specification, the R-S outer code cannot be disabled.

    Codes (TPC), a block coding technique that is a 2- or 3-dimensional array of block codes. Comtech EF Data has chosen to implement an FEC codec based on TPC. Encoding is relatively straightforward, but decoding is a very complex process requiring multiple iterations of processing for maximum performance to be achieved.

  • Page 401: D.7 Sequential (Fast Option)

    SLM-5650A Satellite Modem Revision 8 Appendix D MN-SLM5650A Sequential (FAST Option) Although the method of convolutional coding and Sequential decoding appears to be very similar to the Viterbi method, there are some fundamental differences. To begin with, the convolutional encoder is said to be systematic – it does not alter the input data, and the FEC overhead bits are simply appended to the data.

    TCC, and so is considered much more desirable for two- way, interactive satellite communications applications. In August 1999, Comtech became the first company in the world to offer satellite modems that incorporate TPC. Since its inception, Comtech has continued to develop and refine its implementation of TPC in its products, and now offers a comprehensive range of code rates (from Rate 5/16 to Rate 0.95) and modulations (from BPSK to 16QAM).

    LDPC and a TPC codec need to be offered. Figure D-1. TPC & LDPC Modes Performance (Relative to Shannon Limit) In order to provide a robust set of LDPC codes with varying degrees of latency, the SLM-5650A has implemented three different block sizes: The Ultra Low Latency (ULL) code provides the lowest latency, but worst performance of the three block sizes.

  • Page 406: E.2.2 Ospf Basics

    This means that running OSPF on the hub routers will not add any value. In the example diagram, the SLM-5650A NP Router is essentially a two-port router, thereby requiring that another OSPF node must always be in place “downstream” at the remote.

  • Page 407: E.2.4 Ospf Maritime Use Cases

    The maritime use cases presented here depicts application of OSPFv2 as part of a deployed network of routers that includes the SLM-5650A Network Processor (NP) Interface. The primary objective of these use cases is to describe the process of automatically re-routing traffic when alternative transmission links are available in a maritime environment.

    SLM-5650A Satellite Modem Revision 8 Appendix E MN-SLM5650A E.2.4.2 OSPF Use Case: At Sea When at sea, all traffic is routed to the satellite network. If other communication links such as ship-to-ship or backup lower-speed satellite networks are available, then the OSPF routing protocol selects the best path as defined by link cost.

It has been determined that OSPF can be used with a Vipersat and shared outbound topology by enabling a common router feature: IP Tunneling.

    This, in turn, can limit the overall size of the network, particularly when OSPF dynamic routing protocol is used in the NP Interface. In order to increase the flexibility and scalability of the satellite network with SLM-5650A Satellite Modems, BPM (Bridge Point-to-Multipoint) Mode, an optional FAST feature, has been introduced in the NP Interface’s FW-0000051L Ver.
