Abstract :
This paper investigates the performance of orthogonal frequency-division multiplexing (OFDM) systems applying linear minimum mean-square-error (LMMSE) based channel estimation for coherent detection. We analyze and discuss the robustness of the estimator´s mean-square error (MSE) performance under estimator-to-channel statistics mismatch and derive a closed form expression of the mean bit-error rate (BER) for coherent binary signaling. Different cases of single antenna and diversity reception over Rayleigh and Rician fading multipath channels are considered
