Millimeter-wave radio-over-fiber system based on two-step heterodyne technique.
We theoretically demonstrate an improved two-step-heterodyne-based, millimeter-wave, radio-over-fiber system. With the millimeter-wave mixer and a fiber Bragg grating located in the base station, two-step heterodyne is achieved. The proposed scheme has the merit of good system performance and high suppression of unwanted frequency tones, which is verified by numerical simulations.
