Transmission of LTE signals using optical frequency multiplication by millimeter-wave photonic technology

چکیده
In this paper, performance of long term evolution (LTE) over fiber system is investigated by optical frequency multiplication (OFM) method to generate high-order millimeterwave (mm-wave) using a dual-electrode Mach-Zehnder modulator (DE-MZM) in radio over fiber. Here, optical double sideband subcarrier (DSBSC) scheme is adopted to overcome fiber dispersion-induced RF power fading. Experimental results demonstrated that error vector magnitude (EVM) can achieve less than 13.5% with 16QAM LTE signal in a wireless transmission distance of 1m.

Photonic millimeter-wave frequency multiplication based on cascaded four-wave mixing and polarization pulling.
A technique for the frequency multiplication of microwave signals based on the combination of two optical nonlinear phenomena in a single nonlinear fiber is investigated. Multiple four-wave mixing is used to generate harmonics on an externally modulated optical carrier while polarization pulling through stimulated Brillouin scattering is used to filter the desired harmonics. Microwave signals i...

Data transmission in optical systems and increased transmission distance capacity benefit by using optical amplification wavelength division multiplexing (WDM) technology. The combination of four waves (FWM) is a non-linear effect in the wavelength division multiplex (WDM), when more than two wavelengths of light in a fiber launch will occur. FWM amount depends on the channel, the channel spaci...
