A method for simulating an interference measurement in a communication system is provided to measure an interference amount between adjacent channels by modeling a non-linear power amplifier using polynomials. A receiver model of an interference amount measurement simulating apparatus includes a baseband filter(311), an LNA(Low Noise Amplifier)(312), mixers(313,314), an oscillator(315), a phase shifter(316), and a demodulator(317). The baseband filter filters a received signal. The LNA non-linearly amplifies the filtered signal. A restored bit stream is outputted through the mixer, the oscillator, the phase shifter, and the demodulator. The mixer is modeled according to a standard receiver model. The interference amount measuring simulating apparatus adopts a direct conversion scheme without using an intermediate frequency.
