Paper Abstract

This paper proposes a low complexity near optimal antenna selection scheme based on minimum error rate to improve the performance of multiple-input multiple-output (MIMO) systems. For the independent and identically distributed (i.i.d.) channel, it only needs a sorted QR decomposition compared with the optimal antenna selection algorithm, which requires an exhaustive search of the pseudo inverse of the channel matrix. For the correlated channel, the proposed algorithm achieves good performance by utilizing correlated matrix characteristic. The novel algorithms achieve good performance that is very close to the optimal algorithm, decrease the computational complexity greatly, improve the performance of the receivers, and almost no capacity loss. Simulation results demonstrate that the proposed antenna selection algorithm achieve excellent performance.
