Implementation of Various Error Detection and Correction Techniques in Communication

Abstract

To achieve high performance and better Quality Of data transmission, error detecting and correcting techniques are used. There are many different errors detecting and correcting techniques are available. It can improve the performance as well as the quality of the data transmitted. When a digital signal is transmitted between two systems, the signal gets distorted because of the addition of noise to the transmitted signal. The noise can introduce an error is the binary train of bit travelling from one system to the other. This means that a 0 may change to 1 or a 1 may change to 0. This error can become serious problems with the accuracy and performance of the digital system. Therefore, it is essential to detect and correct the errors. In digital communication errors are introduced during the transmission of data from the transmitter to receiver due to noise or some other reasons. The reliability of data transmission gets severely affected and distorted because of these added errors on data. The detection and correction of transmission error added one or more than one extra bits during the time of transmitting the signal. The extra bits are known as parity bits. These parity bits detect or sometimes correct the errors.
