Ultrawideband performance of spatial multiplexing

Inhalt:
The performance of various spatial multiplexing schemes in ultrawideband pulse based (UWB) binary antipodal modulations is investigated. It is shown that the favourable spatial decorrelation properties of UWB signals allow to decouple spatial channels very effectively, and to reach excellent performance under moderate complexity at the receiver. The work presented here considers several detection methods such as zero forcing, MMSE, and maximum likelihood in order to cope with inter-channel interference. Inter symbol interference is investigated as well, and is shown to be moderate unless of extreme rates. Simulations based on a full double directional channel model exemplify these results.
