• We propose a class of multiple input multiple output (MIMO) systems using the transmit diversity pre-combining (TDPC) scheme, assuming perfect channel state information (CSI) at a transmitter. In such a class of systems, each transmitter antenna is weighted independently according to the channel condition so that the Euclidean distance between the closest symbols at a receiver could be maximized under a total transmit power constraint. We also introduce an effective space-time trellis code (STTC) for the proposed class of MIMO systems. From computer simulations, we see that incorporating both the TDPC scheme and the proposed STTC outperforms the MIMO system using only the TDPC scheme and the conventional STTC-MIMO system.
