An optical carrier generation approach for cellular millimeter-wave radio systems

Art optical carrier generation approach is presented for cellular millimete r-wave radio systems. The well-known methods distribute the millimeter wave signal via fibers. They have drawbacks because they need very high-speed p hotonic components that are expensive. This problem is over come by the new approach utilizing an optically transmitted low-frequency reference signal to generate the millimeter wave carrier. The new approach applies inexpens ive photonic components and is less sensitive to the fiber dispersion.
