Development Of Error Control Coding Technique In Digital Communication System
Journal Title: International Journal of Engineering, Science and Mathematics - Year 2012, Vol 2, Issue 4
Abstract
During digital data transmission in digital communication system, noise is added and physical defects in the communication medium can cause random errors during data transmission. Error coding is a method of detecting and correcting these errors to ensure information is transferred intact from its source to destination. Error coding is used for fault tolerant computing in computer memory, magnetic and optical data storage media, satellite and deep space communications, network communications, cellular telephone networks, and almost any other form of digital data communication. Error coding uses mathematical formulas to encode data bits at the source into longer bit words for is transmission. Decoding of the code word is possible at side of receiver. The extra bits in the code word provide redundant bit, according to the coding scheme used, will allow the destination to use the decoding process to determine if the communication medium’s expected error rate, signal to noise ratio and whether or not data retransmission is possible. Faster processors and better communications technology make more complex coding schemes, with better error detecting and correcting capabilities, possible for smaller embedded systems, allowing for more robust communications. The proposed title discloses a novel approach for detection and correction of binary stream transmission errors such as random errors and bursts errors in digital communication systems. The fault detection and correction will be accomplished by Linear Block Code, Convolution Code or concatenated Code Error-Control Coding techniques.
