The authors consider a large wireless ad hoc network in which each multi-antenna transmitting node sends multiple independent streams to different receivers in a Poisson field of interferers. They provide exact expressions and simplified approximations on the outage probability, contention density, and transmission capacity for dirty paper coding with perfect Channel State information (CSI) as a means to investigate the fundamental limits of multiuser MIMO random networks. They show that superlinear capacity scaling with the number of antennas/streams may at best be achieved using partial interference cancellation at the receive side at the expense of CSI at the transmitter.
