In coding theory, a linear code is an error-correcting code for which any linear combination of codewords is also a codeword. Linear codes are traditionally partitioned into block codes and …
In the rst section we develop the basics of linear codes, in particular we introduce the crucial concept of the dual of a code. The second and third sections then discuss the general …
We will begin by results on the existence and limitations of codes, both in the Hamming and Shannon approaches. This will highlight some criteria to judge when a code is good, and we …
Codes like this take exponential space to describe. In applications, we’d like explicit codes which have polynomial-time computable encoding. The most im-portant class of explicit codes are …
16.1 Linear coding De nition 16.1 (Linear code). Let X =Y =Fn k ∶ → ∀ ∈ q, M=q . Denote the codebook by C <{c u∶ = ∈ u Fk q. A code f Fk q F n q is a linear code if u Fkq, c u uG(row …
We can use algebra to design linear codes and to construct efficient encoding and decoding algorithms. The absolute majority of codes designed by coding theorists are linear codes.
Coding theory is an important study which attempts to minimize data loss due to errors introduced in transmission from noise, interference or other forces. With a wide range of theoretical and …
We will study a class of codes called linear block codes, because their structure o ers several advantages. Linearity will allow an easier analysis of the error correcting ability of a code. …
