[文摘]:The use of simulated annealing to optimize the trellis structure of the next-state map of the decoder finite-state mechine in trellis waveform coding is proposed. The generalized Lloyd algorithm is proposed for the design of codewords. The results are far better than those obtained with vector quantizers and finite-state vector quantizers. (C.D.)
