Spatial Correlation in SM-MIMO-UWB Systems Using a Pre-Equalizer and Pre-Rake Filter
In this paper, we investigate the impact of the spatial correlation on the performance of the spatial multiplexing (SM) Multiple-Input Multiple-Output (MIMO) Ultra-WideBand (UWB) system in which both the pre-equalizer and pre-Rakefilter are deployed at the transmitter. The combination of the pre-equalizer and the pre-filter is to mitigate the Multiple-Stream Interference caused by transmitting several independent data streams simultaneously and the Inter-Symbol Interference while the receivers are kept simple. In order to reduce the complexity of the transmitter, the selective-pre-Rake and the partial-pre-Rake filter are considered. Simulation results show that good performance can be achieved with a limited number of Rake fingers.
