A slotted ALOHA spread spectrum system with adaptive receivers
P.B. Rapajic, Branka S. Vucetic · 2002
A slotted ALOHA direct sequence spread spectrum system with random signatures is considered. The system is applicable in cases where a large number of terminals transmit to a single hub station like in cellular digital radio, personal mobile systems and wireless LANs. It is shown that significant improvements in packet throughput capacity are obtained if the adaptive receiver structures are used. Systems used for the comparison are the spread spectrum slotted ALOHA system and the conventional slotted ALOHA system.
