Abstract:
1. A signal restoring apparatus, comprising: a transmitter transmitting a transmission signal to a satellite communication device; a band spread signal generator generating a band spread signal for estimating the transmission signal included in a reception signal when the transmission signal is received while being included in the reception signal transmitted from a counterpart terminal through the satellite communication device and transmitting the band spread signal to the satellite communication device; a first receiver receiving the band spread signal transmitted from the satellite communication device; a second receiver receiving the transmission signal transmitted from the counterpart terminal through the satellite communication device; a signal estimator estimating the transmission signal included in the reception signal transmitted from the counterpart terminal on the basis of the transmission signal transmitted by the transmitter, the band spread signal transmitted by the band spread signal generator, and the band spread signal received from the satellite communication device; and a signal remover removing the transmission signal estimated by the signal estimator from the reception signal element transmitted from the counterpart terminal.
