Space-time trellis codes with two, three and four transmit antennas in quasi-static flat fading channels

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. We propose two groups of new 4- and 8-PSK STTCs with two to four transmit antennas based on these two design criteria, respectively. Simulation results show that increasing the number of transmit antennas in general provide large performance improvement.
