In Chapter I-13, we looked at ways of coding messages so that if in the transmission an error occurred in one of the digits of a coded word, the receiver would be able to correct the error. Those codes, called Hamming codes, were based on defining coded words as vectors of solutions in ℤ2 to sets of linear equations.

“HiTech” devices, which permeate our life, carry out an infinite number of operations thanks to the information stored inside. The memory contained in these devices, like the memory of human beings, is neither infallible nor eternal. We all live with these devices, accepting the risk that, every now and then, they might fail.

The year 1983 witnessed the introduction of one of the most successful consumer products of all time – the Compact Disc (CD) digital audio system. It was engineering on the grand scale – the use of new material for the optical discs, a solid state laser to read digital information, optical servomechanisms for tracking, and electronics for error ...

Error bits are added to data either to correct or to detect transmission errors. Normally, the more bits that are added, the better the detection or correction. Error detection allows the receiver to determine if there has been a transmission error. It cannot rebuild the correct data and must either request a retransmission or discard the data.

This chapter deals with the problem of reliable transmission of digitally encoded information through an unreliable channel. In a way all channels are not completely reliable. Even the best telecommunication systems connecting numerous information centres in various countries have some non-zero error rate.

The identification number schemes we discussed in the previous chapter give us the ability to determine if an error has been made in recording or transmitting information. However, they are limited in two ways. First, the types of errors detected are fairly restrictive, e.g. single digit errors or interchanging digits.

The problem of adding reliability to data has already been mentioned in Section 2.12. This appendix discusses general methods for detecting and correcting errors. Reliability is, in a sense, the opposite of data compression since it is achieved by increasing data redundancy. Nevertheless, many practical situations call for reliable data, so a good data

Our aim now is to construct codes C with good transmission-rates R and low error-probabilities PrE, as promised by Shannon’s Fundamental Theorem (§5.4). This part of the subject goes under the name of Coding Theory (or Error-correcting Codes), as opposed to Information Theory, which covers the topics considered earlier.
