Apparatus and method for restoring a transmission signal from a reception signal transmitted through a satellite communication device
Provided are a signal restoring apparatus that can restore a reception signal of a counterpart terminal and increase frequency band efficiency by estimating its own transmission signal from a reception signal transmitted from a counterpart terminal through a satellite communication device and removing the estimated transmission signal, and a method thereof. The signal restoring apparatus according to the exemplary embodiment of the present invention includes: a transmitter transmitting a transmission signal to a satellite communication device; a band spread signal generator transmitting a band spread signal to the satellite communication device; a signal estimator estimating the transmission signal included in a reception signal transmitted from a counterpart terminal through the satellite communication device on the basis of the transmission signal and the band spread signal; and a signal remover removing the estimated transmission signal from the reception signal.
