In this Letter the combinatorial optimisation algorithm known as simulated annealing is used for the optimisation of the trellis structure of the next-state map of the decoder finite-state machine in trellis waveform coding. The generalised Lloyd algorithm which finds the optimum codebook is incorporated into simulated annealing so that near-optimum coding systems are designed. Comparison of simulation results with previous work in the literature shows that this method yields better coding systems than those published in the literature.
