Optical Heterodyne Analog Radio-Over-Fiber Link for Millimeter-Wave Wireless Systems [PDF]
Journal of Lightwave Technology, 2021 Optical heterodyne analog radio-over-fiber (A-RoF) links provide an efficient solution for future millimeter wave (mm-wave) wireless systems. The phase noise of the photo-generated mm-wave carrier limits the performance of such links, especially, for the transmission of low subcarrier baud rate multi-carrier signals.
