Abstract

This paper presents a new algorithm that ensures low complexity implementation of a blind ST Rake receiver for DS-CDMA. The algorithm is applicable for both periodic and non-periodic spreading sequences provided that the system utilizes two layers of code separation: a spreading code layer and a scrambling code layer. The new method consists of two kinds of recursions: PAST recursions for a desired signal vector up-date and IUS-like recursions for a correlation matrix of interference and noise up-date. The proposed method maintains performance of a blind batch mode eigenanalysis method, while ensuring convergence and tracking properties of a RLS optimal combiner
