Skew Convolutional Codes [PDF]

open access: yesEntropy, 2020
A new class of convolutional codes, called skew convolutional codes, that extends the class of classical fixed convolutional codes, is proposed.

Divergence coding for convolutional codes [PDF]

open access: yesMATEC Web of Conferences, 2017
In the paper we propose a new coding/decoding on the divergence principle. A new divergent multithreshold decoder (MTD) for convolutional self-orthogonal codes contains two threshold elements.

On Skew Convolutional and Trellis Codes [PDF]

open access: yesarXiv, 2021
Two new classes of skew codes over a finite field $\F$ are proposed, called skew convolutional codes and skew trellis codes. These two classes are defined by, respectively, left or right sub-modules over the skew fields of fractions of skew polynomials over $\F$.

A class of convolution codes

open access: bronzeInformation and Control, 1963
This paper describes a class of infinite convolution codes which are designed to minimize the time required to recover from an erasure burst on the binary erasure channel. It is shown that for any given rate, there exists a unique optimum erasure burst correcting code.

Treatment planning with a 2.5 MV photon beam for radiation therapy

open access: yesJournal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Purpose The shallow depth of maximum dose and higher dose fall‐off gradient of a 2.5 MV beam along the central axis that is available for imaging on linear accelerators is investigated for treatment of shallow tumors and sparing the organs at risk (OARs) beyond it.

Convolutional Goppa codes [PDF]

open access: yesIEEE Transactions on Information Theory, 2006
We define Convolutional Goppa Codes over algebraic curves and construct their corresponding dual codes. Examples over the projective line and over elliptic curves are described, obtaining in particular some Maximum-Distance Separable (MDS) convolutional codes.

On behaviors and convolutional codes [PDF]

open access: yesIEEE Transactions on Information Theory, 1996
It is well known that a convolutional code is essentially a linear system defined over a finite field. In this paper we elaborate on this connection. We define a convolutional code as the dual of a complete linear behavior in the sense of Willems (1979).

LDPC convolutional codes based on braided convolutional codes [PDF]

open access: yes2008 IEEE International Symposium on Information Theory, 2008
We introduce and analyze new constructions of LDPC convolutional codes and their tail-biting versions which are obtained from braided convolutional codes. The basic ideas behind the encoding and decoding architectures for these codes are presented. Additionally, asymptotic results concerning the iterative thresholds are shown for different ensembles ...
