Adaptive power control and mobile station for use in a cellular communications network

摘要

A spread spectrum base station comprising an automatic gain control (AGC) circuit having an input configured to receive a received spread spectrum signal and gain control the received spread spectrum signal to produce a gain controlled signal; a correlation circuit having an input configured to receive the gain controlled signal and correlate the gain controlled signal with a code to produce a despread signal; a power measurement and comparator circuit configured to receive the despread signal and a control level of the AGC circuit and processing at least the despread signal and the control level to produce a processed signal and comparing the processed signal with a threshold to produce a comparison signal, the comparison signal used to produce a power command; and a multiplexer for multiplexing the power command with a signal for transmission over an antenna.
