A Line Coding Scheme for Reducing Timing Jitter in Wdm Soliton Systems

چکیده
INTRODUCTION: In WDM soliton systems, the main sources of timing jitter (TJ) include the Gordon-Haus (GH) effect, soliton-soliton collisions (SSC), the acoustic effect, and the polarization mode dispersion. Although TJ from the GH effect is random from pulse to pulse, other sources lead to nonrandom TJ. Because the time displacements from the nonrandom sources highly depend on the pattern of transmitted data and the introduced bit errors are highly correlated, it is possible to decrease the correlated bit errors by using a coding scheme that has code words with a special data pattern. Several different approaches such as fiber dispersion management [ 11, [2], jitter-tracking demultiplexer

Sliding Window Criterion Codes and Concatenation Scheme for Mitigating Timing-Jitter-Induced Errors in WDM Fiber Transmissions
We propose a concatenated coding scheme, which effectively reduces bit errors induced by soliton–soliton collisions (SSC) in wavelength division multiplexing (WDM) soliton transmission systems. A block line coding scheme, the sliding window criterion (SWC) code, is developed based on the nature of SSC-induced timing jitter in soliton communications. We show, by simplified collision model simula...
متن کاملA Suitable Coding Scheme for Broadband Power-line Communication
This paper introduces three coding strategies for using the Luby Transform (LT) code in a relay aided power-line communication scheme. In the first method, the relay decodes the received packets and re-encodes them for transmission towards the destination. In the second method, the relay only forwardes a random linear combination of its received packets towards the destination, while in the thi...
متن کاملAnalysis of soliton collisions in a wavelength-division- multiplexed dispersion-managed soliton transmission system.
Timing jitter induced by soliton collisions is the leading nonlinear penalty in wavelength-division-multiplexed (WDM) dispersion-managed soliton transmission. Through analysis and numerical simulations we show that consecutive complete collisions together with partial collisions at the system output cause approximately the same amount of timing shift as partial collisions at the system input. W...
متن کاملA Filtering Approach for Reducing Timing Jitter Due to the Acoustic Effect - Lightwave Technology, Journal of
We introduce a signal processing approach to compensate for the timing jitter produced by the acoustic effect in soliton communications. The other main sources of timing jitter, the Gordon–Haus effect and the polarization effect, are inherently stochastic. By contrast, the acoustic effect is deterministic and becomes the dominant source of bit error rates in standard soliton systems when the bi...
متن کاملSuppression of the acoustic effect in soliton information transmission by line coding.
The acoustic effect significantly increases the timing jitter of solitons and the bit-error rates in communication lines. We suggest the transmission of information with fixed-length blocks that contain an equal number of ones and zeros to suppress acoustically induced timing jitter. It is shown theoretically that this approach will significantly enhance the performance of systems with bit rate...
