1. A method for anti-jamming using a decoy signal, the method comprising:
allocating, in connection with a request for transmission of the true information signal, a first frequency band to a true information signal including true information;
when communication channel information allocated to a jammer is received, allocating a second frequency band to a decoy information signal including fake information based on the received communication channel information and outputting the decoy information signal using the allocated second frequency band and the true information signal using the allocated first frequency band, respectively, wherein the allocated second frequency band is free from overlapping the first frequency band; and
when the communication channel information allocated to a jammer is not received, amplifying bandwidth of the first frequency band through a spread spectrum and allocating, as the second frequency band, a portion of the amplified bandwidth of the first frequency band to the decoy information signal and outputting the decoy information signal using the allocated second frequency band which is the portion of the amplified bandwidth of the first frequency band and the true information signal using the allocated first frequency band, respectively,
wherein the true information signal using the allocated first frequency band is outputted after outputting the decoy information signal.
