Abstract :
We present a novel access scheme called CDMA/CS-CF (code division multiple access/code sense for collision free access), which can transmit two kind of traffic i.e. voice and date efficiently. This scheme avoids the collision of packets that occur in CSMA (code sense multiple access), and can assign codes fairly to terminals. This assignment of codes to terminals is operated autonomously by terminals themselves. This scheme can improve the characteristics of throughput and access delay. We evaluate the performance of CDMA/CS-CF compared with CDMA/PRMA, and show the validity, numerically
