摘要

本文研究了基于线性最小均方误差(LMMSE)的信道估计在正交频分复用(OFDM)系统中的相干检测性能。我们分析和讨论了估计器的均方误差(MSE)性能在估计器与信道统计不匹配情况下的鲁棒性，并推导出相干二进制信令的平均误码率(BER)的封闭表达式。考虑了在瑞利和瑞利衰落多径信道上单天线和分集接收的不同情况。

Mean bit-error rates for OFDM transmission with robust channel estimation and space diversity reception

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.
