Transmission capacity of wireless ad hoc network with non-parametric linear MMSE receiver

Recent works on ad hoc network study have shown that achievable throughput can be made to scale linearly with the number of receive antennas even if the transmitter has only a single antenna. In this paper, we put forth an approach achieving linear scaling of the transmission capacity in the practical ad hoc network without loss of transmission efficiency. The key feature to make our approach effective is to exploit the autocorrelation of the received signal for the MMSE receiver. From the transmission capacity analysis as well as numerical simulations, we show that the proposed non-parametric linear MMSE receiver brings substantial performance gain over existing multiple receive antenna algorithms.
