Abstract

In [9] the combination of multitone modulation with direct sequence spectrum spreading has been introduced. In the present paper we analyze the problem of multi-user detection for such systems in the presence of multipath and multiple access interferences. Two types of decision feedback structures are derived for an MSE criterion. The performance of the two systems is obtained for a constrained comparison and the near-far resistance of the detectors is demonstrated in asynchronous scenarios for two types of channels
