IEEE International Symposium on Information Theory
作者: Yasunaga, K Fujiwara, T Osaka Univ Grad Sch Informat Sci & Technol Suita Osaka 5650871 Japan
Relations between the local weight distributions of a binary linear code, its extended code, and its even weight subcode are presented. In particular, for a code of which the extended code is transitive invariant and ... 详细信息

EURASIP JOURNAL ON ADVANCES IN SIGNAL PROCESSING 2011年 第1期2011卷 1-14页
作者: Lim, Meng-Hui Teoh, Andrew Beng Jin Toh, Kar-Ann Yonsei Univ Sch Elect & Elect Engn Coll Engn Seoul 120749 South Korea
Biometric discretization extracts a binary string from a set of real-valued features per user. This representative string can be used as a cryptographic key in many security applications upon error correction. Discret... 详细信息

QUASI-CYCLIC subcodeS OF CYCLIC CODES
收藏 引用
SIAM JOURNAL ON DISCRETE MATHEMATICS 2017年 第2期31卷 1454-1475页
作者: Belfiore, Jean-Claude Guneri, Cem Ozkaya, Buket Telecom ParisTech Dept Comelec 46 Rue Barrault F-75634 Paris 13 France Sabanci Univ Fac Engn & Nat Sci TR-34956 Istanbul Turkey
We completely characterize possible indices of quasi-cyclic subcodes in a cyclic code for a very broad class of cyclic codes. We present enumeration results for quasi-cyclic subcodes of a fixed index and show that the... 详细信息

In this paper, we consider linear subcodes of RMr, m whose bases are formed from the monomial basis of RMr, (m) by deleting Delta K monomials of degree r where Delta K < ((m)(r)). For such subcodes, a procedure for... 详细信息

作者: Harada, Masaaki Saito, Ken Tohoku Univ Grad Sch Informat Sci Res Ctr Pure & Appl Math Sendai Miyagi 9808579 Japan
We show that any ternary Euclidean (resp. quaternary Hermitian) linear complementary dual [n, k] code contains a Euclidean (resp. Hermitian) linear complementary dual [n, k - 1] subcode for 2 <= k <= n. As a con... 详细信息

IEEE TRANSACTIONS ON INFORMATION THEORY 1991年 第6期37卷 1706-1707页
作者: HOU, XD Department of Mathematics and Statistics Wright State University Dayton OH USA
Let C be a binary linear code with covering radius R, and C0 a subcode of C of codimension i. An upper bound is obtained for the covering radius of C0 in terms of R and i. When C0 = {0}, the bound becomes the sphere c... 详细信息
