Spread spectrum base station

Abstract

A spread spectrum base station comprises 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 has 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 is configured to receive the despread signal and a control level of the AGC circuit. The circuit processes at least the despread signal and the control level to produce a processed signal and compares the processed signal with a threshold to produce a comparison signal. The comparison signal is used to produce a power command. A multiplexer multiplexes the power command with a signal for transmission over an antenna.

 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.    
   
   
       2 . A method comprising: 
 receiving a spread spectrum signal;    gain controlling the received spread spectrum signal by an automatic gain control (AGC) circuit to produce a gain controlled signal;    correlating the gain controlled signal with a code to produce a despread signal;    processing at least the despread signal and a control level of the AGC circuit producing a processed signal;    comparing the processed signal with a threshold to produce a comparison signal;    producing a power command using the comparison signal; and    multiplexing the power command with a signal for transmission over an antenna.
