摘要：

The design of wireless communication systems under holistic power models has been being a hot topic in green communications. In this letter, we shall investigate the antenna selection in multi-stream MIMO with circuit power consumption. The difficulty lies in the fact that the optimal active antennas can only be selected by exhaustive search. To reduce the complexity, two iterative properties of MIMO capacity with antenna selection under a holistic power model are first derived in this letter. An efficient iterative antenna selection algorithm can then be obtained directly from these properties. This algorithm enjoys a low complexity, and can be applied to both the transmitter and receiver. Simulation results will verify that the proposed algorithm achieves the near-optimal performance compared to exhaustive search.
