ABSTRACT:
A cordless telephone system connectable to the public switched telephone network having a base station and one or more handsets communicating with the base station by an RF link utility time division duplex direct sequence spread spectrum modulation technique, having a digital variable rate automatic gain control loop. The gain is varied by changing the scale factor for the discriminator output. A high gain scale factor is used during signal acquisition. When the signal has been acquired, a low scale factor is utilized during signal tracking. The controller in the base station and in the handset causes gain use of the different scale factor at the appropriate time.
