| Abstract(in English) | In visible light communications using light emitting diodes (LEDs), non-linear distortion caused by LED non-linearity degrades transmission quality. This paper proposes a compensation method for non-linear distortion of LED circuits in which orthogonal frequency division multiplexing (OFDM) transmission is employed. This method uses peak power reduction of OFDM signals and in-band filtering (IBF) to reduce non-linear distortion noise. Error vector magnitude (EVM) with the method is evaluated by computer simulations. The results show that the method can reduce non-linear distortion noise power by 7.1dB and improve EVM by 4.6%. |
