Abstract:
A base station comprising:an automatic-gain-control (AGC) circuit, responsive to a received signal, for generating an AGC-output signal, with the received signal including a plurality of spread-spectrum user signals and an interfering signal; for each of the plurality of spread spectrum user signals: a correlator coupled to the AGC circuit for despreading the AGC-output signal using a code of that spread spectrum user signal; a power-measurement circuit coupled to the correlator, for processing the despread AGC-output signal as a received-power level; a comparator coupled to the power-measurement circuit for generating a comparison signal using a threshold and the received-power level; and a power-command circuit coupled to the comparator and responsive to the comparison signal for generating a power-command signal; and an antenna; and a transmitter coupled to the antenna and the power-command circuit for transmitting the power-command signals; and wherein each of the spread spectrum user signals having an associated setpoint of a signal to noise ratio based on a service option, and at least one of the spread spectrum user signals having a different setpoint from another of the spread spectrum user signals.
