Accurate closed-form approximation of BER for OSTBCs with estimated CSI on spatially correlated rayleigh fading MIMO channels

In this contribution, we present a novel accurate closed-form approximation for the bit error rate (BER) of orthogonal space-time block codes (OSTBCs) employing quadrature amplitude modulation with Gray-mapping on spatially correlated Rayleigh fading …

Analysis and efficient evaluation of the BER of OSTBCs with imperfect channel estimation in arbitrarily correlated fading channels

An analysis of the exact bit error rate (BER) performance of orthogonal space-time block codes (OSTBCs) with maximum-likelihood detection in the presence of channel estimation errors is presented. The possibly correlated coefficients of the …
