摘要: We present a novel linear precoder design based on the minimum pair-wise error probability (PEP) criterion for general space-time block coded (STBC) MIMO systems. The channel state information at transmitter consists of mean and transmit antenna correlation matrices. Approximate joint diagonalization reveals "average eigenstructure" shared by These average eigenvectors turn out to be left singular vectors matrix. right matrix depend code. values correspond power allocated each mode, which depends statistics Precoder examples non-orthogonal STBCs simulation results are provided illustrate achieved performance gain.
