研究目的
To enhance both the physical-layer security and the transmission performance in OFDM-PON using chaotic discrete cosine transform.
研究成果
The proposed chaotic DCT precoding scheme effectively enhances the physical-layer security and improves the OFDM transmission performance, with a demonstrated improvement in receiver sensitivity by ~1.5 dB (BER@10-3). The scheme provides a high key space of ~10837 and does not require additional sideband information, making it a promising solution for next-generation OFDM-PON.
研究不足
The scheme's security and performance improvements are demonstrated under specific conditions (13.3 Gb/s, 16-QAM, 20 km SSMF). The applicability and effectiveness under different conditions or higher data rates are not explored.
