System capacity optimization of multiple traffic in reverse link of CDMA

摘要

In a W-CDMA system that enables multimedia, it is necessary to consider about multiple traffic composed of voice and data. Because the interference equalization effect by law of large numbers is not acquired as data rate becomes high, system capacity decreases. High-speed data rate is assumed in the inside of the circle of radius r (km) and low-speed data rate is assumed in the other area inside the cell. In each cell, parameter r (km) associated with high-speed transmission area is varied from 0(km) to 2(km) simultaneously. We have shown optimum radius to maximize the capacity.
