摘要： Disclosed are a signal distortion component adjusting apparatus and method capable of adjusting error vector magnitude of subcarriers of a predetermined position by adjusting a signal distortion component occurring while decreasing a peak to average power ratio (PAPR) in a communication system of an orthogonal frequency division multiplexing (OFDM) technology or an orthogonal frequency division multiple access (OFDMA) scheme, and a system using the same. The present invention includes a signal distortion component adjusting unit to add an additional signal distortion component Pe((n+N/2) % N) to a signal distortion component e(n) that is obtained by subtracting a threshold Th value, set to decrease peak power, from an absolute value of a time domain signal x(n) of an input signal, and to thereby adjust the signal distortion component. The present invention may transmit a highly reliable signal by adjusting error vector magnitude of subcarrier of a frequency domain.
