Abstract

A new code design method for the inner code of bit interleaved serially concatenated trellis coded modulation (SCTCM) is proposed. The new design method is based upon the characteristics of bit interleaved coded modulation with iterative decoding (BICM-ID). We use the fact that the BICM encoder can be seen as an SCTCM encoder with a one-state inner code. New design rules for SCTCM are obtained by extending the design principles of BICM-ID to be valid for more than one state. The system considered is SCTCM of rate 2 bits/symbol with 8PSK signaling over the additive white Gaussian noise (AWGN) channel
