摘要：
A Least-Squares based channel estimation algorithm is proposed for Relay-Assisted wireless Multiple-Input Multiple-Output (MIMO) channels. The method consists of a sequence of LS-problems with the purpose to arrive to a computationally efficient solution. The performance of the proposed algorithm is evaluated as a function of the input Signal-to-Noise Ratio (SNR) for randomly generated Rayleigh flat fading channels. Finally, we study the effect of the channel estimation error on the performance of a MIMO Zero-Forcing receiver in order to verify the presented analysis.
