Abstract :
CDMA can offer significant advantages in wireless environments, especially when large capacity and wide range of service rates must be supported. This paper proposed a CDMA-slotted ALOHA system, in which all transmitters used the same PN sequence but with different chip phases and packets can be captured and received because of the autocorrelation property of the PN sequence. Then its channel throughput is analyzed. Analysis and simulation results show that the maximum channel throughput of this system is much greater than pure S-ALOHA system and multiservices can be supported with guaranteed QoS
