ABSTRACT:
A multiphase communication system for simultaneously transmitting plural binary digits employs one or more error-check bits which perform an encoding on the conveyed information over a plurality of digit intervals. The information and error check digits are then communicated via a transmission channel--as by amplitude modulating phase-orthogonal carriers.
Upon reception, the incoming information and error check digits are decoded, and supplied to error syndrome circuitry which corrects errors which may arise from time to time during data transmission.
