Abstract
We consider the performance of orthogonal and non-orthogonal space-time block codes (STBCs) over arbitrarily correlated Rayleigh fading multiple-input multiple-output (MIMO) channels. A pairwise error probability (PEP) bound of arbitrary STBC is derived. Based on this PEP bound, we design a precoder to improve the performance of the orthogonal and non-orthogonal STBC over arbitrarily correlated channels.
