DEVICE FOR CONTROLLING CLOSED LOOP POWER IN SATELLITE MOBILE COMMUNICATION SYSTEM AND METHOD THEREFOR

摘要

PURPOSE: A device for controlling a closed loop power in a satellite mobile communication system and a method therefor are provided to previously calculate a power error after a loop delay time by using a pilot channel for downlink power control and to generate a power control command based on the calculated power error. CONSTITUTION: A converter(110) converts a power control command received from a base station into a power control width. A loop delay compensator(120) outputs a final power control width including a channel change after a loop delay for the received power control width. A channel change measurer(130) receives power of a pilot channel, and measures a channel change. A tab coefficient generator(140) generates a tab coefficient of the loop delay compensator(120) by using the channel change of the power of the pilot channel and a frequency of power control.
