Performance of a TD-SCDMA cellular system in the presence of circuit and packet switched services

We analyze the performance of a time-division synchronous code-division multiple access (TD-SCDMA) system. In particular, we investigate the impact of packet switched applications (for instance Web browsing sessions) on the overall performance of the network. Here, we quantify the degradation of the voice users' quality in the presence of packet data services and vice versa. Finally, we investigate the impact of some power control parameters on the overall quality and we show that these parameters should be carefully chosen to balance the quality of voice and data users.
