Several criteria to design good space-time trellis codes (STTCs) have been developed but an exhaustive search is still required to obtain the best codes. In this paper, we propose a new and fast method to design the best STTCs for 2n-PSK modulations. This method is an extension of the set partitioning proposed by Ungerboeck applied for multiple input multiple output (MIMO) systems. Based on this design method, new 4-PSK and 8-PSK codes are proposed and compared to the best known codes.
