Design criteria on space-time trellis codes (STTC's) in fast fading channels have been derived in [1]: the Distance Criterion and the Product Criterion. The design criteria in [1] are based on optimizing the pairwise error probability (PWEP). However, a frame error rate (FER) of STTC's depends on the distance spectrum. In this paper, we propose new design criteria on STTC's based on the distance spectrum in fast fading channels. The proposed design criteria are based on the product distance distribution for a high signal-to-noise ratio (SNR) and the trace distribution for a low SNR, respectively. Moreover, we propose new STTC's by the computer search based on the proposed design criteria in fast fading channels. By the computer simulation, we show that the proposed design criteria are more useful than the product criterion in [1] in fast fading channels. We also show that the proposed STTC's achieve better FER than the conventional STTC's in fast fading channels.
