Abstract

Aiming at the nonlinear distortion problem in DC offset optical orthogonal frequency division multiplexing(DCO-OFDM) system, this paper proposed a DCT-S peak-to-average ratio(PAPR) suppression algorithm based on discrete cosine transform(DCT) and scaling. The algorithm changed the power distribution probability by DCT transform to reduce the signal envelope range. And then adaptively scaled the time domain signal to better adapt to the dynamic range of the LED, reduced the system peak-to-average ratio, and thus suppressed the nonlinear distortion. The simulation results show that compared with the traditional algorithm, the algorithm could greatly reduce the peak-to-average ratio of the DCO-OFDM system and reduce the bit error rate under the premise of the LED transmit power.
