A memoryless precoder is designed for orthogonal spacetime block codes for multiple-input multiple-output channels exhibiting joint transmit-receive correlation. Unlike most previous similar work which concentrate on transmit correlation only and pair-wise error probability metrics, the precoder is designed to minimize the exact symbol error rate as function of the channel correlation coefficients, which are fed back to the transmitter, and the correlation may or may not follow the so-called Kronecker structure. The proposed method can handle general propagation settings including those arising form a cooperative macrodiversity (multi-base) scenario. We present two algorithms. This first is suboptimal, but provide a simple closed-form precoder that handles the case of uncorrelated transmitters, correlated receivers. The second is a fast-converging numerical optimization which covers the general case. The results show the superiority of the exact SER metric over the PEP as a precoding metric and the impact of "non-Kronecker" channels in the overall performance.
