Abstract
We investigate the performance of a closed-loop multiple-input multiple-output (MIMO) architecture featuring recursive spatial multiplexing (RSM) in the presence of co-channel interference. RSM is effective even when the MIMO channel varies arbitrarily from frame to frame transmission. The RSM scheme evades the noise enhancement inherent in zero forcing (ZF) and minimum mean squared error (MMSE) based receivers and also avoids the increasing complexity that arises in V-BLAST receivers. Using Monte-Carlo simulations, it turns out that RSM outperforms the conventional ZF and MMSE receivers and is an interesting approach in the presence of co-channel interference.
