Error Detecting and Error Correcting Codes
Bell System Technical Journal, 1950The author was led to the study given in this paper from a consideration of large scale computing machines in which a large number of operations must be performed without a single error in the end result. This problem of “doing things right” on a large scale is not essentially new; in a telephone central office, for example, a very large number of ...

On the Trustworthiness of Error-Correcting Codes
IEEE Transactions on Information Theory, 2007The use of error-correcting codes protects data against accidental or intentional errors, but to what extent can a decoded message be trusted? To answer this question, one has to take the role of the receiver. First, the maximum number of errors Lambda acceptable for decoding is fixed. With the weight distribution, the probability of false decoding can

Metacyclic error-correcting codes
Applicable Algebra in Engineering, Communication and Computing, 1995The group codes are ideals of group algebras. Let \(G\) and \(H\) be groups of the same order, \(F\) be a finite field, let \(FG\) and \(FH\) be the corresponding group rings. The combinatorial equivalence is an \(F\) vector space isomorphism \(\gamma: FG\to FH\) induced by a bijection \(\gamma: G\to H\). Codes \(C1 \subseteq FG\) and \(C2 \subseteq FH\

The purpose of this paper is to develop more general techniques for the synthesis of error-correcting codes that dispense with the requirement that coding elements and operations must be associated with finite fields. This approach permits an extension of the class of coded messages and coding operations and leads in certain cases to a reduction of ...

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.

Multiple error-correcting WOM-codes
2010 IEEE International Symposium on Information Theory, 2010A Write Once Memory (WOM) is a storage medium with binary memory elements, called cells, that can change from the zero state to the one state only once. Examples of WOMs are punch cards, optical disks, and more recently flash memories. WOM-codes were first presented by Rivest and Shamir and are designed for efficiently storing and updating data in the ...

Coding schemes are presented that provide the ability to locate computational errors above a prescribed threshold while using analog resistive devices for approximate real vector–matrix multiplication. In such devices, the matrix is programmed into the device by setting an array of resistors to have conductances proportional to the respective entries ...

Error-Correcting Codes in Projective Space
2008 IEEE International Symposium on Information Theory, 2008The projective space of order n over the finite field Fq, denoted Pq(n), is the set of all subspaces of the vector space Fn q. The distance function d(U,V) = dim U + dim V - 2 dim(UcapV) turns Pq(n) into a metric space. With this, an (n, M, d) code C in projective space is a subset of Pq(n) of size M such that the distance between any two codewords ...

Codes for the correction of 'clustered' errors
IEEE Transactions on Information Theory, 1960A method is described which permits the systematic construction of codes capable of error-free transmission, provided errors occur in "clusters" of limited duration. The method is valid for error clusters of any prescribed duration. The codes are relatively easy to implement and decoding operations are straightforward.
