Abstract: A bi-directional transmission configuration based on optical frequency multiplication is presented for millimeter-wave radio-on-fiber systems. At CS, the phase of lightwave is modulated by sweeping sine wave together with basedata. At BS, the input lightwave is divided into two branches composed of periodic optical filter, photodiode and bandpass filter operating at different parameters with relative branch. A millimeter-wave signal modulated by basedata can be generated at one branch, while a reference millimeterwave oscillator is produced at the other. The scheme can minimize CS, does not need a millimeter-wave local oscillator at BS, and can depress link dispersion.
