Experimental Investigation of Direct-Detection Optical Orthogonal Frequency-Division Multiplexing Transmission System

全光采样ofdm系统性能分析

“…Orthogonal frequency division multiplexing (OFDM) [1,2] has attracted significant interest as a future high-speed communication system due to its high tolerance for optical fiber nonlinearity and its high spectral efficiency (SE) [3] . In traditional optical systems, discrete Fourier transform (DFT) and digital-to-analog/analog-to-digital conversion are realized in the electrical domain, which is limited by the electronics processing speed.…”
