Abstract
A near ideal noise whitening filter for a time-varying CDMA system is considered. The structure of the ideal noise whitening filter is studied and the metric function for tree search detection is derived. The ideal noise whitening filter for a time-varying CDMA system depends on unknown, future system parameters and is therefore difficult to realize. A near ideal, realizable noise whitening filter is proposed as a solution
