Inter-Signal Distortion Analysis in Multidimensional QAM-MDPSK Modulation Optical Access Transmissions

چکیده
We report a multi–dimensional quadrature amplitude modulation with M-ary differential phase shift keying (QAM-MDPSK) for optical access network transmission systems employing Mach–Zehnder modulator (MZM) and (PM) in direct detection system. Even though several problems that occur QAM-DPSK single MZM were solved, inter-signal distortion between two modulations remains when the signal is converted into an intensity detection. To maximize capacity of QAM-MDPSK, effect QAM-MDPSK need to be analyzed optimization. Mathematical analysis simulations performed evaluate distortion. Furthermore, experimental on proposed has been verify analysis.

Mitigation of nonlinear transmission effects for OFDM 16-QAM optical signal using adaptive modulation.
The impact of the fiber Kerr effect on error statistics in the nonlinear (high power) transmission of the OFDM 16-QAM signal over a 2000 km EDFA-based link is examined. We observed and quantified the difference in the error statistics for constellation points located at three power-defined rings. Theoretical analysis of a trade-off between redundancy and error rate reduction using probabilistic...

متن کاملReceiver for QAM Modulation
In Internet data transmission, the throughput of 45 Mbps is achieved. Now the goal is to increase the data rate further to 100 Mbps and beyond. We designed a Frequency Division Multiple Access system for that and realized it using Q-Dot technology. The principal reason for coherent demodulation in LAN is the size of PLL in QDot circuit. It also allows higher capacity than 1⁄2 achieved so far. 1...
