A Novel Scheme for Optical Millimeter-Wave Generation Based on Double-Sideband Modulation

Performance Evaluation of Optical Carrier Suppression Radio over Fiber System through Modulation Index Enhancement

“…ROF technology can make the advantages of the optical fiber transmission and millimeter-wave combined, relieve the problems of wireless millimeter-wave system's limited transmission distance [1~4] . To produce high quality millimeter-wave signal is the key technologies to make the millimeter-wave ROF system realized [3,4]. Different prototypes of MZM can generate the optical mm-wave with different spectra, such as double sideband(DSB), optical carrier suppression(OCS), and single sideband(SSB),while each of them has different immunity capacity for the fiber dispersion [3][4][5].The DSB optical mm-wave suffers not only from the fading effect but also from the time shift of the code caused by the sidebands' walk-off [6].Although the OCS optical mm-wave and the SSB optical mm-wave with the signal carried by both the optical carrier and its sideband is immune to fading, time shift of the code limits its transmission [4][5][6].…”

Effect of Modulation Index of Mach-Zehnder Modulator on Single Sideband Radio over Fiber System

“…So, the optical modulation of the mm-wave signal onto light wave is an essential technique in the radioover-fiber (RoF) system. The RoF technology can be combined with the advantages of fiber optic transmission and millimeter-wave, alleviate the problem of limited transmission distance of wireless millimeter wave systems [1][2][3][4] . The millimeter-wave signal is one of the key technologies for achieving the millimeter-wave the RoF system of generating high-quality.…”
