Abstract :
We analyze an integrated voice and data system over a CDMA unslotted ALOHA with channel load sensing protocol, considering the effect of each traffic. We find that the threshold for the number of data transmissions is very effective to improve both the throughput performance for data and the Erlang capacity for voice users. Furthermore, to optimize this system, we define the system capacity. As a result, we obtain an optimum threshold for data to make the best use of the channel capacity
