摘要：

We propose a robust multi-mode linear precoder based on minimum bit error rate (MBER) selection criterion for multi-input-multi-output (MIMO) systems when transmitter only acquires the fading correlations of antennas. The key point of the scheme is that the number of substreams and modulation mode change adaptively to minimize the mean of BER by using channel correlation matrix. In addition, we analyze two special cases with very high or low correlation coefficients. Simulation results state that the proposed scheme selects the most powerful spatial mode and improves the system performance significantly.
