Two strategies to increase the forward link capacity of CDMA systems are compared analytically, and by simulation, with a conventional CDMA system. The strategies are based on reducing the data rate of selected mobile connections. The impact of the propagation environment on the capacity gain of each method is discussed. The comparison shows that maximum capacity gain is achieved when there is large difference between powers allocated to different mobile terminals in the cell.
