A novel compound code is designed for the popular multidimensional (M-D) Wei trelliscode [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(-6) about 2.2-dB additional net gain has been obtained over the conventional scheme of the 4-D 16-state NVei code at a spectral efficiency of 6.7871 bit/T.
