Abstract

Most of the Applications for the DVB-S2 (Digital Video Broadcasting) standard operate at relatively high symbol rates where the inherent latencies introduced by FEC decoding are of little concern. The normal operating range for DVB-S2 in broadcast applications is typically 10 to 30 MBaud. There are however some applications, in particular Radio Amateur Satellite Service applications, where symbol rates well below 1 MBaud are of interest. At these lower symbol rates the latency inherent in FEC decoding the relatively large DVB-S2 frames can be of significant concern, particularly when interactive two-way voice communication is involved. This paper discusses the various latencies associated with DVB-S2 applications and several methods
that are available to reduce such latencies for applications operating in the 80 kBaud to 1 MBaud range.
