Suppression of the acoustic effect in soliton information transmission by line coding.

چکیده
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 rates per channel higher than 20 Gbits/s.

A 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 کاملAcoustic Study of an Auditorium by the Determination of Reverberation Time and Speech Transmission Index
The quality of the communication between teachers and students and ultimately, of classroom education itself, is closely linked to the acoustic quality of the auditorium. This acoustic quality can be characterized based on the reverberation time (RT), speech transmission index (STI) and the sound insulation. In this context, an acoustic study was conducted in an auditorium located in the Higher...
متن کاملA Line Coding Scheme for Reducing Timing Jitter in Wdm Soliton Systems
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 tr...
متن کاملAcoustic effect and correlated errors in soliton information transmission.
The acoustic effect signif icantly increases the timing jitter of solitons in communication lines. We calculate the correlation in near-neighbor soliton time shifts that result from the acoustic interaction and show that the acoustic effect can cause correlated errors that cannot be corrected with standard, simple error-correction codes such as the Hamming code.

In this paper with use of Particle in Cell (PIC) simulation method in one dimension the dynamic of ion acoustic soliton is studied. in this method the ions are monitored as particles and the electrons are assumed to be in thermal equilibrium. The dispersion relation of ion acoustic waves is investigated. The results are in good agreement with analytical results showing that in linear regime our...
