The gain of using multiple antennas for setting up communication over a wireless medium has been widely acknowledged in the literature, starting with the seminal works. For point-to-point channels, the performance of multiple antenna systems is quite well understood by now; in particular, the optimal tradeoff between reliability and rate (also known as Diversity-Multiplexing Tradeoff or DMT) of such systems at high SNR was analyzed in detail. In wireless networking situations, less is known in general about the communication strategies that allow reaching the optimal performance in terms of both reliability and rate.
