We investigate how to improve link quality without degrading data rate by exploiting tradeoffs between diversity and spatial multiplexing gains in multi-input multi-output ad-hoc networks. When the set of input rates for a MIMO network is given, we propose that maximizing the minimum diversity gain among the links provides a reasonable solution to optimize the overall link error probability when there is a reasonably high signal to noise ratio. We verify the performance using simulation based on a modified ns2.
