Robust Multiuser Detection Based on Local Likelihood Search
Recall that in Section 3.4 we introduced a
nonlinear multiuser detection method based on local likelihood search, which
offers significant performance improvement over linear multiuser detection
methods with comparable computational complexity. When combined with the
subspace technique, this method also leads to a nonlinear group-blind multiuser
detector. In this section we discuss the application of such a local likelihood
search method in robust multiuser detection and group-blind robust multiuser
detection. The materials in this section were developed in [455, 456].
