Convolutional Goppa Codes [PDF]

IEEE Transactions on Information Theory, 2003
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 ...

Optimized Generalized LDPC Convolutional Codes [PDF]

Entropy
In this paper, some optimized encoding and decoding schemes are proposed for the generalized LDPC convolutional codes (GLDPC–CCs). In terms of the encoding scheme, a flexible doping method is proposed, which replaces multiple single parity check (SPC ...

Quantum Convolutional Error Correction Codes [PDF]

Physical Review A, 1998
I report two general methods to construct quantum convolutional codes for quantum registers with internal $N$ states. Using one of these methods, I construct a quantum convolutional code of rate 1/4 which is able to correct one general quantum error for ...

Convolutional Polar Codes [PDF]

, 2017
Arikan's Polar codes attracted much attention as the first efficiently decodable and capacity achieving codes. Furthermore, Polar codes exhibit an exponentially decreasing block error probability with an asymptotic error exponent upper bounded by 1/2. Since their discovery, many attempts have been made to improve the error exponent and the finite block-

Divergence coding for convolutional codes [PDF]

MATEC 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.

LDPC convolutional codes based on braided convolutional codes [PDF]

2008 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 ...
