A memoryless precoder is designed for Orthogonal Space-Time Block Codes (OSTBCs) for Multiple-Input Multiple-Output (MIMO) channels exhibiting joint transmit-receive correlation. Unlike most previous similar works which concentrate on transmit correlation only and Pair-wise Error Probability (PEP) metrics: the precoder is designed to minimize the exact Symbol Error Rate (SER) as function of the channel correlation coefficients, which are fed back to the transmitter. The correlation is arbitrary as it may or may not follow the so-called Kronecker structure. The proposed method can handle general propagation settings including those arising from a cooperative macro-diversity (multi-base) scenario.
