In this paper MIMO ad hoc wireless network performance in terms of signal-to-interference-plus-noise-ratio(SINR) for two physical layers models is considered. We analyze and discuss the performance of MIMO spatial multiplexing with dominant eigen value transmission, when the the beam forming weights are chosen as 1) dominant eigenvector, and 2) adaptive weights that adjusted to instantaneous interference scenario. Comprehensive analytical analysis of SINR in output of a receiver node for a mentioned transmision schemes in the presence of interferer nodes are done. We show that with adaptive beam forming approach the interferer nodes signals can be significantly suppressed achieving higher network performance. The simulation result confirm our analysis.
