Simulation of the Burst Error Correction using Matlab

Shikha Kuchhal

Abstract :

The paper contains a report on Simulation of the Burst Error Correction. Most of the practical communication channels such as magnetic storage systems, telephone lines, optical discs used to store digital data such as CD,DVD etc are affected by errors which are concentrated in a certain locality rather than randoms errors. These errors may be due to physical damage such as scratch on a disc or a stroke of lightning in case of wireless channel. Such errors occur in a burst (called as burst because they are occurring in many consecutive bits). The methods used to correct random errors are inefficient to correct such burst errors. This motivates burst error correcting codes. The idea of interleaving is used to convert convolutional codes used to random error correction for burst error correction. During the message transmission, an impairment occurs from time to time i.e. an error arises which is caused by interfering signals during the transmission. The situation requires that the respective coding is adapted as much as possible to the given conditions of the transmission. The convolutional coding is suitable for the correction of burst errors. However, the procedure of the majority of burst error correction solutions is very demanding. This article therefore explains a complex procedure of design and simulation in Matlab on a specific case which is suitable for its simplicity and makes the explanation of the lesson easier.
