A joint source/channel coding system is constructed using trellis coded quantization (TCQ) and trellis coded modulation (TCM). Identical trellises are used in the TCQ and TCM systems, and a straightforward mapping of TCQ codewords to TCM symbols is presented which guarantees that Euclidean squared distance in the channel is commensurate with quantization mean-square error (MSE). Hence, likely TCM error events of small Euclidean distance cause only small increase in overall source coding MSE.
