ABSTRACT:
A digital communication system for the transmission and reception of digitized information and capable of operation over a broad range of data rates without need for clock or timing information. The system employs as an input signal a multiple amplitude level signal having zero average amplitude which is converted to a multiple phase coded signal having zero average phase. The phase coded signal is transmitted over a communication path and upon reception is directly reconverted to a multiple amplitude level form without need for recovering clock or timing information.
