Space-time trellis codes (STTC) using product distance codes with delay diversity structure are studied and the optimal condition of product distance codes is proposed. The upper bound of the optimal product distance of codes on 8-PSK modulation is derived. The performance of the STTC using various product distance codes found through a systematic code search is compared with that of delay diversity.
