Matched Filter as Pre-processing Tool for Multi-user Detection in DS-CDMA System

摘要

Due to the demand for cellular wireless services, recent interests are in techniques, which can improve the capacity of CDMA systems. On such technique is multi-user detection. Multi-user Detection (MUD) is the intelligent estimation/demodulation of transmitted bits in the presence of Multiple Access Interference (MAI). In this paper, we will show the role of matched filter used as pre-processing tool for MUD in DS-CDMA system.
