Adaptive Blind Sequence Detection for Time Varying Channel
Mohammad Patwary, Predrag Rapajic, Ian Oppermann · Kluwer Academic Publishers eBooks · 2005
In this paper a new blind sequence detection algorithm has been proposed. It has a significant robustness against bit shift ambiguity in comparison to existing blind sequence detection algorithm with coded system. The Viterbi algorithm is extended to a blind form with new branch metric criterion. Significant gain (as much as 8dB) has been achieved in Signal to Noise Ratio (SNR) at the BER level of 10 -3 due to the resistance against the error propagation.
