Abstract: PURPOSE: A device for separating overlapped frequency transceiving signal and a satellite communication using the same are provided to use frequency twice in satellite communication which has inefficient frequency resource. CONSTITUTION: A phase/delay estimator(140) estimates phase error and transmission path delay time from a duplicated signal. A phase/delay controller(130) performs FIFO(First In First Out) timing control. A modulation signal generator(110) converts the compensated transmission data into a modulated signal. A pre-distorter(120) distorts the modulated signal. A frequency shifter(150) performs frequency shift for the pre-distorted modulated signal. An adder(160) eliminates the frequency shifted modulated signal from the overlapped signal.

Abstract: PURPOSE: An active repeater for anti-jamming and a method thereof are provided to reconfigure a hopping frequency in a frequency band except a frequency of a jamming frequency band. CONSTITUTION: A jamming information reception unit(220) receives jamming frequency band information from a ground control station, and a hopping frequency reconfiguring unit(230) uses the received jamming frequency band information to extract a hopping frequency band except the jamming frequency band from the whole frequency bands of an active repeater. The hopping frequency reconfiguration unit reconfigures the hopping frequency of the active repeater within the extracted hopping frequency band.
