| Abstract(in English) | In this paper, we focus on voice and data integration over a CDMA Unslotted ALOHA with Channel Load Sensing Protocol. The blocking probability and the Earlang capacity for voice users, throughput performances for data packet are evaluated with consideration of the effect of the other media. To find a tradeoff between evaluations for voice and data, we define the system capacity which is the sum of data throughput and voice Earlang capacity. Consquently, we can find the optimum data offered load to make the best of system capacity over maintaining the voice quality to the condition that the maximum bit error rate for voice is always kept under a value of 0.01 and the blocking probability for voice users is always less than 1%. The investigation of the effect of voice activity detection (VAD) is also presented. |
