RELAY DEVICE, COMMUNICATION SYSTEM, AND COMMUNICATION METHOD

Abstract

A relay device performs signal relay between a transmission device that transmits a first modulated signal obtained by modulating a first error-correction code sequence generated by performing a first error-correction encoding process on an information sequence and a reception device serving as a destination of the first modulated signal. The relay device includes a first soft demodulator that generates a first soft demodulated sequence including reliability information corresponding to the first modulated signal; a second error-correction encoder that performs a second error-correction encoding process on an information sequence including the first soft demodulated sequence to generate a second error-correction code sequence; and a second modulator that transmits a second modulated signal obtained by modulating the second error-correction code sequence.
