摘要
Abstract
For a multiple input multiple output system, antenna selection saves the RF chains which are expensive. This paper addresses the antenna subset selection for multiple antenna systems in correlated channels. Due to high complexity of conventional selection scheme, we propose to embed Hadamard transform in the RF chains before the selection. Furthermore, a decomposition selection scheme is proposed based.on the symmetry of Hadamard transform. According to the analysis of Monte Carlo simulation, the channel capacity changes slightly while the complexity of selection reduces dramatically.关键词
