Improved code design criteria for space-time codes over quasi-static flat fading channels

Design issues concerning the code design criteria of space-time trellis code are discussed and the improved design criteria for space-time trellis codes are proposed. The improved design criteria are designed to minimize the frame error probability. The new codes based on proposed criteria had been successfully designed and simulated. The simulation results show that the performance of new codes based on proposed criteria can be improved compared to some existing codes.
