  Abstract

This paper introduces an encoder design method of Turbo TCM (Trellis Coded Modulation) with symbol puncturing. TTCM consists of two trellis encoders in parallel and modulator. To design a good trellis encoder, we calculate the free distance with the assumption that the punctured symbol is chosen with the equal probability from the subset that consists of signals with the same systematic bit. We develop a search program to find the component encoder which maximizes the free distance. Especially, for 8-PSK with code rate 2/3, we search for the component codes. We find a new encoder which has better BER (bit error rate) performance than that of Robertson ’ s encoder. We verify the results through the simulation.
