An Implementation of Error Minimization Data Transmission in OFDM using Modified Convolutional Code

open access: goldEmitter: International Journal of Engineering Technology, 2016
This paper presents about error minimization in OFDM system. In conventional system, usually using channel coding such as BCH Code or Convolutional Code. But, performance BCH Code or Convolutional Code is not good in implementation of OFDM System.

An efficient algorithm for the reconstruction of punctured convolutional codes [PDF]

open access: goldEURASIP Journal on Wireless Communications and Networking, 2017
Puncturing is one of the methods of increasing the code rate, and the original code before puncturing is called the mother code. Any (N,K) convolutional code is obtainable by puncturing some (n,1) mother codes.

Convolutional Polar Codes [PDF]

open access: green, 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-

Quantum Convolutional Error Correction Codes [PDF]

open access: yesPhysical 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 ...

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.

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.

An Embedding Strategy Using Q-Ary Convolutional Codes for Large and Small Payloads

open access: yesMathematics, 2021
Matrix embedding (ME) code is a commonly used steganography technique, which uses linear block codes to improve embedding efficiency. However, its main disadvantage is the inability to perform maximum likelihood decoding due to the high complexity of ...

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 ...
