Abstract(in English) | Orthogonal frequency division multiplexing (OFDM) signals suffer from nonlinear distortion at the transmitter, in particular high-power amplifiers. As a peak-to-average power ratio (PAPR) reduction technique, Constant Peak-power OFDM (CP-OFDM) has been proposed, which can fix the envelope-peak amplitude to a constnat value while maintaining linearity of the IFFT outputs. Advancing this technique, this paper proposes a nonlinear distortion compensation method by combining it with baseband predistortion in OFDM systems. This paper presents simulation and experimental results which verify that this method decreases out-of-band emission and adjacent channel interference. |
