摘要：
It has been established that the appropriate design parameters for space-time trellis code (STTC) in quasi-static flat Rayleigh fading channels are the rank and determinant criteria or the Euclidean distance criterion, depending on the value of the overall diversity gain. In this letter, we propose two groups of new STTCs with more than two transmit antennas based on these two design criteria, respectively. These new STTCs are shown to achieve large performance improvements over the ones with two transmit antennas.
