摘要：
A chaotic discrete Fresnel transform (DFnT) precoding scheme is proposed for physical -layer security enhancement in orthogonal frequency division multiplexing passive optical networks (OFDM-PONs). A multi -fold OFDM data encryption is applied in terms of the chaotic scale factor, and chaotic row/column permutations in the DFnT matrix, and the chaos sensitivity creates a huge key space of 10 138 . The peak -to -average power ratio (PAPR) performances of OFDM signals associated with a scale factor in DFnT are fully analyzed. A 38.2 Gb/s OFDM signal transmission with chaotic DFnT is successfully demonstrated over a 20 km standard single -mode fiber (SSMF), where the gain of receiver sensitivity is similar to 2 dB (BER @ 10 -3 ), compared with OFDM without precoding.
