Abstract :
In this paper, an access control scheme on the code shift keying spread spectrum (CSK/SS) random access systems is evaluated. In this system, each user estimates the number of transmitting users based on the received power and decides whether to transmit a packet or not. When a user becomes ready to send, the user estimates the number of transmitting users. If it is equal or less than a certain threshold, q, the user transmits a packet with a probability p = 1. Otherwise, the user transmits a packet with 0 les p < 1. Consequently, it is found that the throughput performance of the CSK/SS random access system improves by applying this access control scheme
