Abstract :
In this paper, we present two novel methods to enable concurrent communications in MIMO networks. First method enables an 802.11n MIMO-OFDM receiver to decode independent data streams from two independent 802.11n transmitters concurrently. It is implemented on real time 802.11n based MIMO-OFDM testbeds and the performance of the technique is examined through both simulation and field trials. Second method is a low overhead Concurrent Communications scheme based on Adaptive Interference Cancellation (CC-AIC), which does not require any explicit channel state information (CSI) between the nodes in the network.
