Spatial Multiplexing With MMSE Receivers in Ad Hoc Networks

The performance of spatial multiplexing systems with linear minimum-mean-squared-error receivers is investigated in ad hoc networks. The authors present new exact closed-form expressions for the outage probability and transmission capacity. These expressions reveal that from a transmission capacity perspective, single-stream transmission is preferable over multi-stream transmission. Multiple antennas can offer significant performance improvements in wireless communication systems by providing higher data rates and more reliable links. A practical method which can achieve high data rates is to employ spatial multiplexing transmission in conjunction with low complexity linear receivers, such as the Minimum-Mean-Squared-Error (MMSE) receiver.
