A Modified Dynamic Antenna Selection Algorithm for MIMO System

摘要：

Channel capacity formula of MIMO system before and after antenna selection is derived. A modified dynamic antenna selection algorithm is presented. This algorithm selects the optimal k antennas based on Water Pouring principle, then the selected k transmitting antennas are redistributed equal transmit power. To verify the algorithm, it is applied to full-rank and rank deficient channel. Numerical results show the algorithm could select the optimal antenna subset in the two cases in a high degree of accuracy without redundant computation time.
