Packet-level iterative detection for SFH communications with Reed-Solomon coding in partial-band interference

A SFH system using Reed-Solomon coding and the parity-bit method is considered with a receiver employing packet-level iterative detection and decoding, and the performance of the system in a channel with partial-band interference is evaluated. It is shown that the packet-level iterative reception technique results in substantially better performance than one-shot detection and decoding at a minimal cost in increased computation at the receiver. The use of an inner differential encoder is also examined, and its inclusion is shown to result in improved performance with packet-level iterative reception. Furthermore, alternative approaches to the parity-bit method are evaluated. Finally, the performance is compared with that of several other choices for coding and either one-shot or iterative decoding in SFH systems
