Abstract

α ve β sıfırdan farklı pozitif tamsayılar olmak üzere, Z_2^α×Z_4^β nın alt grupları olarak tanımlanan Z_2 Z_4-toplamsal kodlar araştırmacılar tarafından son yıllarda oldukça ilgi görmüştür. Bu kod ailesine benzer bir kod sınıfı Z_2^r×(Z_2+uZ_2 )^s üzerindeki kodlardır. Bu kodlar Z_2 Z_4-toplamsal kodlara göre bazı avantajlara sahiptir. Bir kodun tüm kodsözleri aynı ağırlığa sahipse bu kod bir-(sabit) ağırlıklı kod olarak tanımlanır. Bu çalışmada, Z_2^r×(Z_2+uZ_2 )^s üzerindeki relatif iki-ağırlıklı kodlar çalışılmıştır. İlk olarak, iki-mesafeli bir Z_2 Z_2 [u]-lineer kodun Gray görüntüsünün ikili iki-mesafeli bir kod olduğu gösterilmiştir. Daha sonra relatif iki-ağırlıklı bir Z_2 Z_2 [u]-lineer kodun Gray görüntüsün ikili relatif iki-ağırlıklı bir kod olduğu ispatlanmıştır. Ayrıca, bu kodların duallerinin genellikle relatif iki-ağırlıklı kod olmadıkları örneklerle gösterilmiştir. Son olarak, relatif iki-ağırlıklı bir Z_2 Z_2 [u]-lineer kodun yapısı belirlenmiştir.

Relative Two-Weight Z_2 Z_2 [u]-Linear Codes

Abstract

Z_2 Z_4-additive codes, defined as subgroups of Z_2^α×Z_4^β where α and β are positive integers, have been considered by researchers for last years. The family of these codes are similar to the class of codes over Z_2^r×(Z_2+uZ_2 )^s. These codes have some advantages compared to Z_2 Z_4-additive codes. A code is called constant weight (one-weight) if all the nonzero codewords have the same weight. In this study, relative two-weight codes over Z_2^r×(Z_2+uZ_2 )^s are considered. Firstly, it is shown that the Gray image of a two-distance Z_2 Z_2 [u]-linear code is a binary two-distance code. Then, it is proven that the Gray image of a relative two-weight Z_2 Z_2 [u]-linear code, with nontrivial binary part, is a binary relative two-weight code. Also, it is shown that the duals of these codes are not relative two-weight codes generally by using examples. Finally, the structure of relative two-weight Z_2 Z_2 [u]-linear codes are determined.
