Abstract

We propose a new multistage whitener-based detector (MWD) to guarantee low complexity and high performance for multiple-input multiple-output systems. The proposed MWD reduces complexity by detecting two out of NT transmitted symbols in each stage of the whitening process. Furthermore, it can enhance performance by adopting a norm-based selection criterion that considers the instantaneous channel state and interference cancellation using Ci local solutions at the i -th stage of the whitening process. Accordingly, the proposedMWDcan achieve the optimum maximum likelihood detector (MLD)while having a considerably reduced computational complexity compared with the optimal MLD.
