Abstract

In this paper, a novel method is proposed for signal detection and the active users enumeration in asynchronous direct sequence code division multiple access (DS/CDMA) in MULTIPATH FADING channel based on INFORMATION THEORY criteria. There are two main categories of information criteria which are widely used in blind source separation (BSS), Akaike Information Criterion (AIC) and Minimum Description Length (Mlil.) INFORMATION THEORY criteria. We use both of them in the proposed algorithm. Our introduced method needs a simple omni-directional antenna which simplifies receiver's structure and reduces its costs. Also, this exploitation provides us with the ability to use our proposed algorithm in the coherent signal case. Numerical results confirm our claims and the efficiency of algorithm in detection and exact enumeration of active users in low SNRs and multipath environment.
