Packet combining techniques for frequency-hop communication systems with partial-band interference

Two methods for combining packets in frequency-hop spread-spectrum systems that employ interleaving and Reed-Solomon coding are presented and analyzed for the partial-band interference channel. Bounded distance errors-and-erasures decoding and erasure generation by means of Viterbi's (1982) ratio-threshold test are incorporated in the analysis. Results of the analysis show that both combining schemes provide significant gains in throughput.
