Adaptive Receivers for Spread‐Spectrum Systems
Urbashi Mitra · 2003
Abstract Adaptive demodulation algorithms for direct‐sequence code‐division multiple‐Access (DSCDMA) signaling are described herein. The article begins with a review of multiple‐access signaling and DSCDMA modulation. Several key static (nonadaptive) multiuser reception schemes are described and some basic elements of adaptive algorithms are presented. Adaptive receivers for additive white Gaussian noise channels and frequency selective fading channels are provided.
