摘要

提出了一种具有接收机分集的OFDM接收机算法。该接收机采用一种新的两步盲信道估计算法，称为子空间- mmse信道估计器。然后基于估计信道进行最小均方误差线性分集组合。仿真结果表明，该方法可实现1 ~ 3db的性能增益。

Subspace-MMSE blind channel estimation for multiuser OFDM with receiver diversity

A receiver algorithm for OFDM with receiver diversity is proposed. The proposed receiver uses a new two-step blind channel estimation algorithm referred to as the subspace-MMSE channel estimator. Minimum mean square error linear diversity combining is then performed based on the estimated channel. Simulation results show that performance gain of 1-3 dB is achievable by the proposed approach.
