Let us now understand on following which properties a code is said to be of cyclic nature. Property 1: Property of Linearity. According to this property, a linear combination of two codewords must be another codeword.

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 convolutional codes, although turbo codes can be seen as a hybrid of these two types. Linear codes allow for more … Se mer A linear code of length n and dimension k is a linear subspace C with dimension k of the vector space $${\displaystyle \mathbb {F} _{q}^{n}}$$ where $${\displaystyle \mathbb {F} _{q}}$$ is the finite field with q elements. Such a … Se mer As the first class of linear codes developed for error correction purpose, Hamming codes have been widely used in digital communication … Se mer Lemma (Singleton bound): Every linear [n,k,d] code C satisfies $${\displaystyle k+d\leq n+1}$$. A code C whose parameters satisfy k+d=n+1 is called … Se mer Some examples of linear codes include: • Repetition codes • Parity codes • Cyclic codes Se mer As a linear subspace of $${\displaystyle \mathbb {F} _{q}^{n}}$$, the entire code C (which may be very large) may be represented as the span of a set of $${\displaystyle k}$$ codewords … Se mer Codes in general are often denoted by the letter C, and a code of length n and of rank k (i.e., having k code words in its basis and k rows in its generating matrix) is generally referred to as an (n, k) code. Linear block codes are frequently denoted as [n, k, d] codes, … Se mer A code is defined to be equidistant if and only if there exists some constant d such that the distance between any two of the code's distinct codewords is equal to d.
