CDMA系统中,功率控制对于降低系统干扰,提高系统容量和性能具有重要作用。介绍了一种基于信道增益向量的功率控制方案,并通过仿真验证了该功率控制方案的性能。仿真结果表明,该功率控制方案相对于基于数据速率的功率控制方案具有额外的4～6dB的增益。
In CDMA systems, power control plays an important role in reducing system interference and improving system capacity and performance. A power control scheme based on channel gain vector is introduced, and the performance of the power control scheme is verified through simulation. The simulation results show that the power control scheme has an additional gain of 4 ~ 6dB compared to the data rate based power control scheme.
