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 …

Effect of MMSE channel estimation on BER performance of orthogonal space-time block codes in Rayleigh fading channels

We present a simple closed-form expression for the BER of orthogonal space-time block codes (OSTBCs) with MMSE channel estimation, assuming PAM and QAM constellations and flat Rayleigh block fading. The BER expression is exact for a certain class of …
