EFFECTS OF TRANSMISSION CONTROL IN AN INTEGRATED VOICE AND DATA CDMA SYSTEM

In this paper, we focus on an integrated voice and data system over a CDMA Unslotted ALOHA and investigate the effect of transmission contro l for data traffic. We consider Channel Load Sensing Protocol (CLSP) a s a transmission control protocol and investigate the effect of the th resholds, which may differ due to the requirment of each medium. As a result, we find that the threshold assigned for data is very effective to improve both performances of the throughput for data and the Erlan g capacity for voice users, and also. to correspond to the priority fo r both media. Consequently, we obtain an optimum threshold for data to make the best use of the total channel capacity.
