ABSTRACT:
A communication system for transmitting a six-phase modulated signal and including an efficient error correction system suitable for the six-phase modulated signal is disclosed. A transmitting apparatus comprises a ternary error correction encoding circuit for generating a ternary transmit sequence, a parity generation circuit for generating a parity, a parity insertion circuit for inserting the parity into a binary transmit sequence, and a six-phase modulator for performs six-phase modulation. A receiving apparatus comprises a parity generation circuit for generating a parity, a parity separation circuit for separating a received parity, a parity comparison circuit for calculating a difference between the parity and the received parity, a syndrome calculation circuit for calculating a syndrome, a ternary error correction decoding circuit for producing a ternary decoded sequence, a high-order digit correction circuit for producing a binary decoding sequence, and a 6-ary to binary conversion circuit for producing a binary received signal is obtained from the ternary decoded sequence and binary decoding sequence.
