A new DS/TH spread spectrum (SS) system is proposed in this paper. The system is intended to increase the multiaccess efficiency of an SS system by employing time diversity and a new class (multi decoding-erasure-error) forward error correction scheme. Reed Solomon is the basic code employed and an algorithmic demodulation rule is used in conjunction with a modifled majority vote among the outputs of many decoders to flnaliy yield a superior error and throughput performance. We also show in this paper that the extra side information represented by the DS preample acquisition matched fllter output can be used to adjust the thresholds on the demodulation erasure generation process to reflect the instantaneous condition of multi-access interference.
