ABSTRACT:
An improved auto-equalizer technique is disclosed for use in two-way communications systems having terminals which are connected by a communications link having distortion characteristics which are substantially identical for signals traveling in either direction. The technique includes a master modem which is always first to transmit in the system, and one or more remote modems. Each remote modem includes an adaptive filter in the receiver section of the modem which adaptively sets its filter characteristics to be the inverse of the line distortion characteristics. Each remote modem also includes a slave filter in the transmitter section which is also set have filter characteristics which are substantially the same as that of the adaptive filter. The slave filter acts to pre-distort the signals transmitted from the remote modem so that they arrive at the master modem substantially undistorted.
