An Improved Complete Sharing Dynamic Channel Allocation Algorithm in TD-SCDMA System

In this paper, we propose an improved complete sharing (CS) dynamic channel allocation (DCA) algorithm for TD-SCDMA. In the proposed algorithm, the voice service and the data service dynamically share all channel resources in the system, and at the same time, the voice service has the priority to use the channel resources. Simulation results show that compared with the conventional CS algorithm, the proposed algorithm significantly improves the voice service performance.
