Abstract

We propose a new approach to precoding and equalisation for frequency selective MIMO channels by applying a recently proposed broadband singular value decomposition to decouple the NEMO channel matrix into independent frequency selective SISO subchannels. In a second step, ISI present in the subchannels is eliminated using methods reported in the literature. The first step helps to remove not only co-channel interference but also eliminates part of the inter-symbol interference with a very small loss in channel power gain. It also helps to use the system resource more effectively, leading to a better performance. The numerical example given in the paper shows that our proposed method can provide better bit error rate performance than that of the benchmark design. Under a quality of service constraint, our design can achieve higher data throughput and mutual information than that of the benchmark design while maintaining a similar error performance
