Transmit Antenna Selection in Spatial Correlated MIMO Systems with Correlation-Adapted Iterative Receiver

摘要：

In this paper we present a method that combines transmit antenna selection and reduced-constellation detection in spatially correlated MIMO fading channels. To mitigate the performance degradation caused by the use of antenna selection that is based on correlation among columns, we propose an iterative receiver scheme that uses only a subset of the constellation points that are close to the expected symbol value estimated in the previous iteration. The size of the subset can adapt to the maximum correlation of the sub-matrix after the simple antenna selection. The simulation results show a significant advantage both for implementation complexity and for error rate performance under a fixed data rate.
