Research on Outer-loop Power Control Based on Iterative Process in TD-SCDMA

Outer-loop power control is one of the important links in closed-loop power control of TD-SCDMA, it decides the target value of inner-loop power control.PC methods in TD-SCDMA system are discussed, an outer-loop power control algorithm based on iterative process is produced.The closed-loop power control under some conditions such as different channel environments and different control parameters is simulated.It is found that the power control algorithm can effectively improve the system performance.
