چکیده
A soft decoding technique is discussed in this paper to improve the performance of long-distance optical networks (LDOTNs). LDOTNs are affected by phase noise and nonlinearities generated inside fiber. The investigations proposed LDOTN were carried out dual-polarization 16-quadrature amplitude modulation (DP-16QAM), DP-64QAM over single-mode fiber (SMF) digital signal processing (DSP) methodologies. improved presented mechanism SMF based on constellation shaping (CS). CS then compared standard 16-QAM 64-QAM using international telecommunication union-telecommunication (ITU-T) G-652.D G-657.A1 SMF. detecting procedure enables attain significant outcomes.

Soft decoding in optical systems
We consider the application of concatenated codes with interleaver and iterative decoding to optical communication systems. We show how to obtain the optimum log-likelihood ratio to be provided to the soft decoder in the optical channel environment, and compare the performance of a decoder using it with the one employing a Gaussian approximation of the optical channel. Simulation results refer ...

15 صفحه اولLinearisation of Transmitter and Receiver Nonlinearities in Optical OFDM Transmission
In this paper, linearisation of transmitter and receiver nonlinearities of an optical Intensity Modulation/Direct Detection system using digital signal processing is presented and analysed. The system performance is estimated on basis of the signal-to-interference-and-noise ratio. Furthermore, the bit error performance of a linearised system is compared to a non-linearised one.
متن کاملPulse Shaping for a Long-Distance Optical Synchronization System
Next generation free electron lasers aim to generate x-ray pulses with pulse durations down to 30 fs, and possibly even sub-fs. Synchronization of various stages of the accelerator and the probe laser system to the x-ray pulses with stability on the order of the pulse width is necessary to make maximal use of this capability. We are developing an optical timing synchronization system in order t...
