[IEEE 2019 18th International Conference on Optical Communications and Networks (ICOCN) - Huangshan, China (2019.8.5-2019.8.8)] 2019 18th International Conference on Optical Communications and Networks (ICOCN) - Chaotic Discrete Cosine Transform for Physical-Layer Data Encryption in OFDM-PON

摘要： Chaotic discrete cosine transform is proposed to enhance both the physical-layer security and the transmission performance in OFDM-PON. Experimentally, secure transmission of 13.3Gb/s OFDM signals shows a ~1.5 dB (BER@10-3) improvement in receiver sensitivity.
