This paper presents an efficient architecture for a 4-D eight-phase-shift-keying trellis-coded-modulation (TCM) decoder. First, a low-complexity architecture for the transition metric unit is proposed based on substructure sharing. This scheme significantly reduces the required computation without degrading the performance. Then, a new hybrid T -algorithm for a Viterbi decoder is developed by applying a T-algorithm on both branch metrics (BMs) and path metrics (PMs). TCM encoders usually employ… CONTINUE READING
