PERFORMANCE ANALYSIS OF SLOTTED ALOHA CDMA SYSTEM WITH ADAPTIVE MMSE RECEIVERS/

A slotted ALOHA direct sequence spread spectrum system with random sig natures is considered. The system is applicable in cases where a large number of terminals transmits to a single hub station like in cellula r digital radio, personal mobile systems and wireless LANs. It is show n that significant improvements in packet throughput capacity are obta ined if the adaptive receiver structures are used. Systems for the com parison are the spread spectrum slotted ALOHA system and the conventio nal slotted ALOHA system.
