Signal generation schemes for millimeter-wave radio-over-fiber system based on heterodyned unlocked light sources and RF homodyned receiver


Two millimeter-wave radio-over-fiber signal-generation schemes are demonstrated by heterodyning unlocked-lasers and homodyning the detected RF-carrier to cancel phase-noise effects at baseband. The proposed schemes avoid phase/frequency locking, high-speed modulators and local-oscillators at CS and BSs.
