This paper presents a new method for implementing antenna selection in high-throughput wireless LANs (WLANs), addressing two major practical concerns: antenna selection training protocol design, and calibration to solve RF imbalance problems. Specifically, the low Doppler spread of WLAN channels enables us to train all antenna subsets by multiple training packets transmitted in burst; consequently antenna selection techniques can be accommodated in the emerging standards with minimum modifications. In order to deal with RF imbalance, we propose a novel calibration procedure that reduces the performance degradations. The proposed solutions in this paper thus make antenna selection more easily adoptable for high-throughput WLAN systems. |
