Information Theory, Coding and Cryptography

Preface

Information lost means no information. A reliable transmission of information is the basic requirement of communication system. In spite of all the efforts given to the error-free transmission, noise is attributed to communication channel, causing erroneous data at the receiver. It is important that the information at the receiving end is error-free, or if any error occurs, the receiver must detect, locate, and correct the error. Search for the techniques to achieve reliable transmission over noisy communication channel is based on Shannon's theorem at late 1950 that reliable transmission can be achieved with the selection of proper encoding and decoding system, if the signalling rate is less than the channel capacity. This leads to the ...
