Multi-User Detection for Next-Generation CDMA

摘要

The overall objective of this grant was to investigate basic research issues on signal processing for demodulation of multiuser digital wireless communication systems of interest to future U.S. Army terrestrial tactical needs. This study was motivated by the emergence over the past years of the field of multiuser detection from previous ARO-sponsored projects led by the principal investigators. A major goal of this project was to design and analyze detectors that could be used with long-sequence CDMA. This is the Direct- sequence method employed in several civilian and military spread spectrum systems. To that end, random spreading models are used to obtain succinct figures of merit based on congestion and bandwidth.
