Abstract :
This paper proposes an adaptive transmission control scheme for CDMA cellular slotted-ALOHA systems. This scheme adaptively controls the target received power and the processing gain according to both channel load and location of the mobile station. Computer simulation validates the effectiveness of this scheme: the capture effect can be achieved under heavy channel loads, and therefore, throughput performance is improved. Detailed evaluation of throughput, packet reception probability and transmission complete probability is presented. Calculated results show that the proposed scheme has superior characteristics in cellular environments with slow Rayleigh fading channels
