In CDMA systems, due to the talkspurts nature of voice terminals, it is possible to integrate the data terminals with a slight expansion. The difficult, that may arise is the maintenance of the quality and delay dependency on two different media, voice and data. For voice, it, requires real-time delivery with a resonable bit error rates while data requires high qualty transmission but rather careless, for real-time delivery. In this work, we Analyse the system performance of voice and data terminals operating in the same CDMA channel. For analysis, we consider that the voice is transmitted as a form of CDMA packet. In such way, the transmission is occurred only in talk status of voice terminal and the effect of voice activity is completely taken care of. The system is, therefore, considered as CDMA ALOHA system with two different, media.
