1. A receiver apparatus for tracking and rejecting a Transmit (Tx) signal in a wireless communication system, the apparatus comprising:

  • a controller adapted to receive channel frequency information of the Tx signal and to control an operation for tracking and rejecting a frequency of the Tx signal;

    a phase locked loop adapted to generate an oscillation frequency by generating a control voltage according to the channel frequency information of the Tx signal under the control of the controller and to filter a signal corresponding to the oscillation frequency among signals input to a low noise amplifier; and

    the low noise amplifier adapted to amplify power while minimizing noise of the signal filtered by the phase locked loop.
