COMMUNICATION DEVICE, COMMUNICATION METHOD, COMMUNICATION PROGRAM, AND COMPUTER-READABLE RECORDING MEDIUM

摘要

A communication device capable of generating a transmission signal to another station as a desired signal without measuring the delay time caused by the round-trip propagation to the satellite. The communication device comprises a replica signal generating means (a first demodulating section (3), a binarizing section (4), a demodulator (5), and filter (8)) generates a replica signal as a replica of the outbound signal by using the difference ( ) of the power density between the outbound signal and the inbound signal and by demodulating the outbound signal as an unwanted signal, a signal delay section (7) for generating a delay superimposition signal by delaying the superimposition signal by a time necessary for the replica signal generating section to generate the replica signal, and a signal cancel section (8) for canceling the unwanted replica signal generated by the replica signal generating signal from the delay superimposition signal. Thus, the measurement of the delay time is unnecessary.
