Abstract
An interference signal reducing apparatus of a wireless communication system divides a signal that is input through a receiving antenna into a first signal and a second signal having a magnitude larger than that of the first signal and detects a frequency and a magnitude of an interference signal from the first signal, thereby generating an interference removal signal and then adds an interference removal signal to the signal that is input through the receiving antenna and thus reduces a magnitude of the interference signal.
Claims14
An interference signal reducing apparatus comprising:
- a first signal division unit that divides a signal that is input through a receiving antenna of a wireless communication system into first and second signals;
- a detection unit that detects a frequency and a magnitude of an interference signal from the first signal and that generates an interference removal signal using the detected frequency and magnitude;
- and
- a summation unit that adds the interference removal signal to a signal that is input through the receiving antenna and that outputs the added signal.
