Reduced-State Sequence Estimation for Coded Modulation in CPSC on Frequency-Selective Fading Channels

摘要

Reduced-state sequence estimation (RSSE) for trelliscoded modulation (TCM) in cyclic prefixed single carrier (CPSC) with minimum mean-square error-linear equalization (MMSE-LE) on frequency-selective Rayleigh fading channels is proposed. The Viterbi algorithm (VA) is used to search for the best path through the reduced-state trellis combined equalization and TCM decoding. Computer simulations confirm the symbol error probability of the proposed scheme.
