N2 - We study the limiting throughput of an MIMO (multiple-input multiple output) ad hoc network with K simultaneous communicating transceiver pairs. Assume that each transmitter is equipped with t antennas and receiver with r antennas, we show that in the absence of channel state information (CSI) at the transmitters, the asymptotic network throughput is limited by r nats/s/Hz as K → ∞. With CSI corresponding to the desired receiver available at the transmitter, we demonstrate that an asymptotic throughput of t + r + 2√tr nats/s/Hz can be achieved using a simple beamforming approach. Further, we show that the asymptotically optimal transmission scheme with CSI amounts to a single-user water€lling for a properly scaled channel.
