    • A receiver apparatus for tracking and rejecting a Transmit (Tx) signal in a wireless communication system and an operation method thereof are provided. The receiver apparatus includes a controller for receiving channel frequency information of the Tx signal and for controlling an operation for tracking and rejecting a frequency of the Tx signal; a phase locked loop for generating 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 for filtering a signal corresponding to the oscillation frequency among signals input to a low noise amplifier; and the low noise amplifier for amplifying power while minimizing noise of a signal filtered by the phase locked loop.
    • 提供了一种用于在无线通信系统中跟踪和拒绝发送(Tx)信号的接收机装置及其操作方法。 接收机装置包括:控制器,用于接收Tx信号的信道频率信息,并控制用于跟踪和拒绝Tx信号频率的操作; 用于通过在控制器的控制下根据Tx信号的信道频率信息产生控制电压并且对输入到低噪声放大器的信号中对应于振荡频率的信号进行滤波来产生振荡频率的锁相环; 以及用于放大功率同时最小化由锁相环滤波的信号的噪声的低噪声放大器。
