An Adaptive Maximum Likelihood Sequence Estimation Technique for Wideband HF Communications

Performance is presented for a non-real-time (NRT) software coherent binary phase shift keyed (BPSK) receiver using both simulated and recorded HF signals at a bit rate of 2.4 kbps. The receiver consists of: (1) an adaptive matched filter, (2) a maximum likelihood sequence estimator (MLSE) incorporating a modified Viterbi algorithm (MVA), (3) a maximum… CONTINUE READING
