Abstract

A recently proposed differential correlation based acquisition technique, the differential correlator-matched filter (DC-MF) algorithm, results in greater interference suppression by using differential correlators, but is computationally complex. We propose a modification to this algorithm, which reduces the computational complexity with little loss in performance. Simulations, for a multiuser system under varying load conditions have been done.
