Abstract: PURPOSE: A multi carrier system and method for receiving a multi carrier are provided to accumulate the amplitudes of signals, thereby reducing the amount of hardware resources by controlling a signal level. CONSTITUTION: A conversion unit(120) converts an input signal from a time domain to a frequency domain. A signal accumulating unit(130) accumulates the amplitude of the input signal by a preset accumulation interval unit. The signal accumulating unit counts an overflow frequency based on the accumulated amplitude of the input signal. A signal level determining unit(140) generates bit shift information which adjusts the level of the converted signal based on the counted overflow frequency. A signal level adjusting unit(150) adjusts the level of the converted signal according to the generated bit shift information.
