Abstract
Sequential decoding of the channel code in a trellis-coded modulation system with trellis shaping can be used to reduce the system complexity and to achieve high coding gain with large constraint-length codes. It is shown that almost all the shaping gain that can be achieved when Viterbi decoding is used for the channel code can also be achieved when sequential decoding is used for the channel code. It is also shown that the real shaping gain is a function of both the SNR and the spectral efficiency.
