Abstract

A novel compound code is designed for the popular multidimensional (M-D) Wei trellis code [1] combined with a simple parity-check code. Using the iterative Viterbi decoding algorithm, we can achieve a remarkable performance improvement with low computational complexity. Simulation results show that at a bit error rate (BER) of 3.7 x [10.sup.-6] about 2.2-dB additional net gain has been obtained over the conventional scheme of the 4-D 16-state Wei code at a spectral efficiency of 6.7871 bit/T. Index Terms--Iterative Viterbi algorithm, multidimensional TCM, parity-concatenated trellis code.
