Abstract
Along with the multiple-input multiple-output (MIMO) system gains, comes a price in hardware complexity and cost due to multiple RF chains. It is possible to alleviate this cost and at the same time maintain many advantages of MIMO systems by a technique known as antenna selection. In this paper, we propose a new receive antenna selection algorithm which is based on the orthogonal components of the rows of channel matrix. It can achieve very nearly outage capacity with the optimal selection method while keep low computational complexity. Besides, the bit error rate (BER) performance under Space-Time Block Coding (STBC) transmit scheme demonstrates the significant performance of the proposed selection algorithm.
