Abstract
The problem of optics orthogonal frequency division multiplexing (optical-OFDM) communication lies in the peak to average power ratio (PAPR), which seriously affects the quality of communication systems. A composite technique, which combines the Hartley transform and KC companding technique to reduce the PAPR of an optical-OFDM system, is proposed. The proposed technique can obtain the same quality of OFDM signals and offer an improved bit error rate performance by using Hartley transform instead of the traditional Fourier transform, while the computational complexity is almost halved. Theoretical analysis and simulation results show that the proposed technique has a superior performance for reducing the PAPR when compared to the traditional technique.
