Abstract :
For MIMO systems with large number of transmit and receive antennas, a major concern is the requirement for the hardware complexity and computational cost. A promising solution is to employ antenna subset selection. In this paper, we focus on antenna subset selection at the receiver where the antennas are selected to maximize channel capacity. It is shown that our approach has lower computational complexity than the existing receive antenna selection techniques while achieving the similar outage capacity as the optimal selection algorithms. In particular, the dominant complexity in recursions has been lowered in two orders of magnitude.
