Abstract

Abstract

For improving the performance of MIMO system with quasi-orthogonal STBC exploiting the channel knowledge, a new transmitter scheme combining the linear precoding matrix is proposed. Before sending out from the transmit antennas, the information is sent into the space-time encoder, then is processed by a precoder matrix. Exploiting the channel correlation and mean, the linear precoder is designed based on the Pair-wise Error Probability (PEP). Simulation results show that significant gain in BER of the new system can be obtained compared with the unprecoded system.
