Coding Theory

چکیده
♣ Introduction. Coding theory originated with the advent of computers. Early computers were huge mechanical monsters whose reliability was low compared to the computers of today. Based, as they were, on banks of mechanical relays, if a single relay failed to close the entire calculation was in error. The engineers of the day devised ways to detect faulty relays so that they could be replaced. While Richard Hamming was working for Bell Labs, out of frustration with the huge task he was working with, the thought occurred that if the machine was capable of knowing it was in error, wasn’t it also possible for the machine to correct that error. Setting to work on this problem Hamming devised a way of encoding information so that if an error was detected it could also be corrected. Based in part on this work, Claude Shannon developed the theoretical framework for the science of coding theory.
