In coding theory, a cyclic code is a block code, where the circular shifts of each codeword gives another word that belongs to the code. They are error-correcting codes that have algebraic properties that are convenient for efficient error detection and correction. See more Cyclic codes can be linked to ideals in certain rings. Let $${\displaystyle R=A[x]/(x^{n}-1)}$$ be a polynomial ring over the finite field $${\displaystyle A=GF(q)}$$. Identify the elements of the cyclic code See more Before delving into the details of cyclic codes first we will discuss quasi-cyclic and shortened codes which are closely related to the cyclic codes … See more The Hamming(7,4) code may be written as a cyclic code over GF(2) with generator $${\displaystyle 1+x+x^{3}}$$. In fact, any binary Hamming code of the form Ham(r, 2) is equivalent to a cyclic code, and any Hamming code of the form Ham(r,q) with r and q-1 relatively … See more Applications of Fourier transform are widespread in signal processing. But their applications are not limited to the complex fields only; Fourier … See more Now, we will begin the discussion of cyclic codes explicitly with error detection and correction. Cyclic codes can be used to correct errors, like Hamming codes as cyclic codes can be used for correcting single error. Likewise, they are also used to correct double … See more From Hamming distance concept, a code with minimum distance $${\displaystyle 2t+1}$$ can correct any $${\displaystyle t}$$ errors. But in many channels error pattern is not very … See more A constacyclic code is a linear code with the property that for some constant λ if (c1,c2,...,cn) is a codeword then so is (λcn,c1,...,cn-1). A negacyclic code is a constacyclic code … See more WebThere is the long-standing question whether the class of cyclic codes is asymptotically good.
