Analog Coherent-Optical Mobile Fronthaul With Integrated Photonic Beamforming [PDF]
IEEE Journal on Selected Areas in Communications, 2021 We present a mobile fronthaul methodology for the analogue optical transmission of native radio signals with integrated photonic true-time delay for the beam steering of phased-array antennas. Laser-based coherent homodyne detectors and the delay dissemination through ultra-dense wavelength division multiplexing ensure a low complexity at the optical ...
