چکیده

In this paper an attempt is made to study the theoretical fundamentals for Coherent optical orthogonal frequency division multiplexing (CO-OFDM) for high speed, long haul optical transmission and investigated the nonlinear effect of a 16-QAM CO-OFDM and WDM CO-OFDM at 10Gbps data rate. We then demonstrated the transmission performance through simulation for single channel COOFDM and multi-channel WDM CO-OFDM system with 100GHz channel spacing. The simulation results reveal that single channel CO-OFDM has better transmission performance up to 500km of SSMF without dispersion compensation in comparison to WDM CO-OFDM system where the transmission distance reduced to 400km instead of 500km.

Transmission simulation of coherent optical OFDM signals in WDM systems.

In this letter, we first present the theoretical basis for coherent optical OFDM systems in direct up/down conversion architecture. We then demonstrate the transmission performance through simulation for WDM systems with coherent optical OFDM (CO-OFDM) including the fiber nonlinearity effect. The results show that the system Q of the WDM channels at 10 Gb/s is over 13.0 dB for a transmission up...

Power pre-emphasis for suppression of FWM in coherent optical OFDM transmission.

Four-wave-mixing (FWM) due to the fiber nonlinearity is a major limiting factor in coherent optical OFDM transmission. We propose to apply power pre-emphasis, i.e. to allocate the transmitted power non-uniformly among subcarriers in order to suppress the FWM impairment. The proposed technique was numerically investigated for both single channel 15.6 Gbs CO-OFDM transmissions and 7-channel WDM t...

Improved Channel Estimation for DVB-T2 Systems by Utilizing Side Information on OFDM Sparse Channel Estimation

The second generation of digital video broadcasting (DVB-T2) standard utilizes orthogonal frequency division multiplexing (OFDM) system to reduce and to compensate the channel effects by utilizing its estimation. Since wireless channels are inherently sparse, it is possible to utilize sparse representation (SR) methods to estimate the channel. In addition to sparsity feature of the channel, the...

Suppression of Four Wave Mixing Based on the Pairing Combinations of Differently Linear-Polarized Optical Signals in WDM System

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...
