Self-encoded spread spectrum modulation with differential encoding
Yan Kong, Lim Nguyen, Won Mee Jang · 2003
In this paper we analyze self-encoded spread spectrum (SESS) modulation with differential encoding and decoding. We show that this structure eliminates the BER effect of error propagation. We also investigate maximum likelihood sequence detection (MLSD) of SESS sequence using the Viterbi algorithm. The results show that MLSD outperforms the feedback detector in terms of the BER performance.
