Method to compensate for distortions within a multiple access communications system, and terminal station and central station included in such a communications system for performing such a method

Abstract From the Canadian patent

A method is described to compensate for distortions in a communications network wherein a central station is coupled to a plurality of user network terminals via a plurality of communication channels consisting of the cascade connection of a plurality of user network terminal links and a common link. By this method, distortions which are common to all of said communication channels are equalised within said central station whereas, distortions which are only dependent on one respective communication channel are compensated within the respective user network terminal coupled to this respective communication channel, by performing within said respective user network terminal, a pre-correcting …
