Experimental evaluation of an RF-MIMO transceiver for 802.11a WLAN

In this paper we evaluate the real-time performance of a MIMO-enhanced 802.11a transceiver based on analog combining techniques. The aim of this transceiver design is to achieve higher performance than conventional 802.11a systems while keeping costs and power consumption similar. Also, the demonstrator used to carry out this evaluation is presented, as well as its implementation over a dual band MIMO testbed. Moreover, a series of experiments conducted on nomadic indoor scenarios have led us to results that corroborate the expected analog combining benefits.
