On Two Classes of Primitive BCH Codes and Some Related Codes

IEEE Transactions on Information Theory, 2019
BCH codes are an interesting type of cyclic codes and have wide applications in communication and storage systems. Generally, it is very hard to determine the minimum distances of BCH codes.

Second-order coding rate for m-class source-channel codes

2015 53rd Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2015
The second-order coding rate for source-channel codes with m levels of unequal message protection (UMP) is derived. The second-order coding rate takes the form of an optimization problem which reduces to separate source-channel coding rate for m = 2. A procedure for solving the given optimization problem is proposed. The proposed procedure exploits the

Quantum codes from cyclic codes over GF(4/sup m/)

Proceedings. 2001 IEEE International Symposium on Information Theory (IEEE Cat. No.01CH37252), 2001
We provide a construction for quantum codes (Hermitian-self-orthogonal codes over GF(4)) starting from cyclic codes over GF(4/sup m/). We also provide examples of these codes some of which meet the known bounds for quantum codes.

DC/sub m/ codes for constructing t-EC/AUED codes

IEEE Transactions on Computers, 1998
A common method for constructing t-error correcting/all unidirectional error detecting (t-EC/AUED) codes is to append a tail to t-EC code, where the tail is a function of the weight of the codeword. Here, we present a method to reduce the weight distribution of t-EC codes by using a DC/sub m/(k+d, k) code as the input of t-EC code where a DC/sub m/(k+d,

Color encoded display of M code echocardiograms

Journal of Clinical Ultrasound, 1976
AbstractThe need for increased dynamic range of echoes in echocardiography is discussed. A method for acquiring color coded echocardiograms is described and advantages as well as disadvantages are discussed. Typical results of color coded echocardiograms advantagesasare shown.

A coding scheme for m-out-of-n codes

IEEE Transactions on Communications, 1990
A scheme for the construction of m-out-of-n codes based on the arithmetic coding technique is described. For appropriate values of n, k, and m, the scheme can be used to construct an (n,k) block code in which all the codewords are of weight m. Such codes are useful, for example, in providing perfect error detection capability in asymmetric channels ...
