[PDF][PDF] Design of mm-RoF system based on OFM technique with optimized OFDM modulation
R Lin, X Chen, L Zhang, J Ye, Y Song - Chinese Journal of Lasers, 2012 - researching.cn
We present the design of a novel bi-directional millimeter-wave radio-over-fiber (mm-RoF)
system based on the millimeter-wave generation by optical frequency multiplication (OFM).
A dual-drive Mach-Zehnder modulator is used to generate high-order optical side-modes
which beat in the photo-detector, producing a 40-GHz carrier. Over 100-Mb/s orthogonal
frequency division multiplexing (OFDM) modulation scheme is employed. The emphasis is
on developing a mathematical model for optimizing optical modulation index to the Mach …
