英文摘要	Traditional iterative signal clipping (ISC) techniques can reduce the effect of nonlinear clipping noise in nonlinear LED optical-orthogonal frequency division multiplexing (O-OFDM) systems. However, the ISC system requires multiple LEDs to emit light at the same time, which is complicated in synchronization and hardware applications, as the bit error rate (BER) increases with the channel gain difference. An O-OFDM symbol decomposing serial transmission system based on single LED is proposed in this study. The O-OFDM symbol is decomposed by amplitude clipping, followed by serial framing, and it is finally input to single LED. The expression of the system theoretical signal-to-noise ratio is derived and the simulation models using the Monte Carlo bit error rate and the error vector magnitude (EVM) are built. Results demonstrate that the performance of EVM and BER enhance significantly as the number of symbols decomposing increases; however, the communication rate slightly decreases, and the direct current biases will affect the performance of EVM and BER. Furthermore, the proposed system is simple to implement and avoids the problem of BER degradation caused by the channel gain difference. © 2020, Chinese Lasers Press. All right reserved.
