SLM-5650A Satellite Modem

Revision 10

Appendix C

C–9

MN-SLM-5650A

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. This code is available in the data rate range from 32 kbps to 2 Mbps
and is compatible with the CDM-625 ULL code.

•

The Low Latency (LL) code provides modest latency and performance over the data rate
range of 32 kbps to 5 Mbps.

•

The High Performance (HP) code provides the best performance but worst latency. This
code is available from 32 kbps up to 69 Mbps depending on MODCOD. The HP code is
compatible with the CDM-625 LDPC code.

See

Appendix B. OPERATIONAL REFERENCES

for more details on the data rate and symbol

rate ranges supported in each code.
