RECEIVE ANTENNA SELECTION ALGORITHM TO IMPROVE ERROR PERFORMANCE IN MIMO SYSTEMS WITH LINEAR RECEIVERS

摘要

In this paper, a receive antenna selection algorithm inrnMIMO systems with linear receivers is proposed. Thernnumber of selected antennas is not fixed and is chosenrnaccording to channel situation. This algorithm hasrniterative structure and uses a threshold in each step to findrnthe antenna in the worst condition. In the first part of thernalgorithm (algorithm-A), there is no limitation for thernnumber of selected antennas whereas for the second partrn(algorithm-B), the number of selected antennas in eachrnstep is upper bounded. In both parts, it is possible tornadjust the performance by varying a threshold level. Asrnthe simulation results show, the algorithm-A has betterrnerror performance and the algorithm-B could be used forrnpower saving purposes.
