  • A combined power control and data rate adjustment scheme with Minimum Mean Square Error (MMSE) receiver for the 3GPP Wideband Code Division Multiple Access (WCDMA) reverse link is proposed. It can guarantee target SIR while keeps transmit power at the minimum level and faster convergence, resulting an optimal overall system performance. Computer simulation shows that the proposed scheme is appropriate and the optimization algorithm is effective and correct. Simulation results show that, using the proposed algorithm, the capacity of system is increased by about 10% and the speed of convergence is sped up by about 30 % compared with those obtained using MMSE power control algorithm.
