【Abstract】 In view of the characteristics of the TD-SCDMA system,the inner-loop power control algorithms in the system are elaborated,and a power control algorithm based on linear prediction of the input parameters of the power control is also put forward.In combination with open-loop and outer-loop power control,the inner-loop power control under some conditions such as different channel environments and different control parameters has been simulated.It shows that the algorithm can counteract the power loss of path loss and slow fading to a certain extent,so as to benefit the system performance.更多还原
