LMS adaptive filter single-user receiver
2004
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.
