Orthogonal frequency division multiplexing (OFDM) signals suffer nonlinear distortion within the transmitter, in the high-power amplifiers in particular. This paper proposes a nonlinear distortion compensation technique for OFDM signals, which incorporates a baseband predistortion with a constant peak-power OFDM (CP-OFDM). CP-OFDM fixes the envelope-peak amplitude to a constant value while maintaining the linearity of the inverse fast Fourier transform (IFFT) outputs; consequently, the baseband predistorter entirely compensates the nonlinear distortion. Simulation and experimental results verify that the proposed technique significantly reduces out-of-band power emission and adjacent channel interference (ACI) more than 10 dB respectively.
