Abstract:
A low-noise amplification apparatus and method in a receiver in a wireless communication system are provided, in which a main amplifier amplifies a received signal, a sub-amplifier amplifies a third-order harmonic component more strongly than a signal component in the received signal and cancels the third-order harmonic component by combining the amplified signal with the signal received from the main amplifier. A noise eliminator amplifies noise included in the received signal and eliminates the noise by combining the amplified noise with the signal received from the main amplifier or the signal received from the sub-amplifier.
