Abstract:
1. A communication device comprising: a primary modulator that subjects an input signal to primary modulation to generate a primary modulated signal; a secondary modulator that subjects the primary modulated signal to secondary modulation based on a communication scheme to generate a secondary modulated signal; a transmitter that generates a transmission signal based on the secondary modulated signal and transmits the transmission signal; a retransmission request receiver that receives a retransmission request that contains identification information identifying the input signal; an operator that uses a data sequence that is a set of elements of a same number as a number of elements in the input signal and with element values of 1 or 0 to generate operation data whose elements are values of exclusive OR of respective elements of the input signal and respective elements of the data sequence that are at same positions as positions of the respective elements of the input signal; and a retransmitter, if the retransmission request receiver receives the retransmission request, that subjects an input signal identified by identification information contained in the retransmission request to processing by the operator and subjects resulting operation data as the input signal to processing by the primary modulator, the secondary modulator and the transmitter.
