Incoherent Heterodyning of Phase Modulated Signal for Low-cost Millimeter-wave RoF Link
2018 IEEE International RF and Microwave Conference (RFM)(2018)
摘要
This paper investigates an incoherent approach to heterodyne uncorrelated free running optical tones to generate phase modulated (e.g. DPSK) mm-wave signal from regular optical signal at the last miles. Proposed scheme relies on simple electrical delay-and-multiply type demodulator at the customer premise for a LO-free data recovery.
