Chu and Mitra : Analysis of Music - Based Delay Estimators for Ds - Cdma

| Most receiver designs for asynchronous Direct-Sequence Code-Division Multiple-Access systems exploit timing information to simultaneously detect the desired signal and suppress the interference. In this paper, a previously proposed MUSIC delay estimation algorithm is considered which requires no initial information and no exhaustive search of the delays. Based on a Taylor series expansion, approximations of the rst and second moments of the delay estimation error are derived for this MUSIC algorithm. The analysis is alternative and further to that previously performed.
