Algorithms for Majority Decoding of Group Codes
We consider a problem of constructive description and justification of the algorithms necessary for a practical implementation of the majority decoder for group codes specified as left ideals of groupalgebras.

Extended binary Golay codes by a group algebra of one group
Extended binary Golay codes are examples of extreme binary self-dual codes of Type II (linear binary self-dual codes with Hamming distance between arbitrary codewords which are multiples of 4 that has the highest possible minimum Hamming distance among ...

Cryptosystem Based on Induced Group Codes
The code C on a group G, induced by the code N on a subgroup H, has the property that for decoding the code C one can use the decoder for the code N.

Block-coded modulation using two-level group codes over generalized quaternion groups [PDF]
Summary: A length \(n\) group code over a group \(G\) is a subgroup of \(G^n\) under component-wise group operation. Two-level group codes over the class of generalized quaternion groups, \(Q_{2^m}\), \(m\geq 3\), are constructed using a binary code and a code over \(Z_{2^{m-1}}\), the ring of integers modulo \(2^{m-1}\), as component codes and a ...

The group of characters of an elementary Abelian group has been used to define duality between its subgroups, which in turn is extended to duality between group codes.

New Two-Stage Automorphism Group Decoders for Cyclic Codes
Recently, error correcting codes in the erasure channel have drawn great attention for various applications such as distributed storage systems and wireless sensor networks, but many of their decoding algorithms are not practical because they have higher

Codes in Dihedral Group Algebra
Robert McEliece developed an asymmetric encryption algorithm based on the use of binary Goppa codes in 1978 and no effective key attacks has been described yet.

Summary: We construct a class of codes of length \(n\) such that the minimum distance \(d\) outside of a certain subcode is, up to a constant factor, bounded below by the square root of \(n\), a well-known property of quadratic residue codes. The construction, using the group algebra of an abelian group and a special partition or splitting of the group,

LCD codes and LCP of codes from units of group rings
A linear code with complementary dual(LCD) is a linear code such that LCD codes are of greatimportance due to their wide range of applications in consumer electronics,storage systems and cryptography. Group rings have a rich source of units. Alsothe well-

On a relation between GAG codes and AG codes
In this paper, we first give a relationship between generalized algebraic geometry codes (GAG codes) and algebraic geometry codes (AG codes). More precisely, we show that a GAG code is contained (up to isomorphism) in a suitable AG code.
