Recently, a new class of trellis codes called "balanced" space-time trellis codes has been proposed. These codes are "balanced" because they use the points of the MIMO constellation with the same probability. In this paper, we propose a new and simple method to design these codes for 4-PSK and 8-PSK modulations and several transmit antennas. This design method can be easily extended to 2n-PSK modulations. Furthermore, new balanced STTC with 3 and 4 transmit antennas are given with better performance than the previously published codes.
