Switch and stay diversity combining is shown to offer substantial complexity reduction at the cost of modest performance degradation compared to systems with selection diversity. In this work, the performance of multiple input multiple output (MIMO) systems employing switch and stay combining at the receiver is studied. Only 2 antennas are assumed to be present at the receiver. A novel switching algorithm...
We propose a closed-loop spatial multiplexing system with limited feedback and rate control over MIMO fading channels. The transmitter adaptation is designed to maximize spectral efficiency subject to an average bit error rate (BER) constraint by adapting the number of substreams based on a given threshold, and a fixed constellation, which determines the instantaneous rate. The proposed system chooses...
