Software radio technology makes possible the implementation of highly flexible receivers architectures that employ sophisticated signal processing algorithms such as those required for equalization. The implementation of advanced DS-CDMA receivers based on adaptive filter principles is becoming an area of considerable interest. The focus of the paper is the introduction of a dynamically reconfigurable architecture and an adaptive linear receiver for CDMA systems in mobile communication. This paper, presents a flexible single-user receiver that can support a variety of applications and analyses the convergence behaviour of the least mean square (LMS) filter when used in an adaptive code division multiple access (CDMA) detector consisting of a tapped delay line with adjustable tap weights.
