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. In 1984 Arrigo Bonisoli determined the structure of linear one-weight codes over finite fields and … Se mer

NettetGenerator matrix. In coding theory, a generator matrix is a matrix whose rows form a basis for a linear code. The codewords are all of the linear combinations of the rows of this matrix, that is, the linear code is the row space of its generator matrix. Nettet20. mar. 2024 · Linear Block Codes: It is a simple error control coding technique used for error detection and correction. Information data is partitioned into blocks of length K pieces for example Information word. Every information word is then coded into a block of length n bits called a codeword. Here, n > k

When a sender wants to transmit a possibly very long data stream using a block code, the sender breaks the stream up into pieces of some fixed size. Each such piece is called message and the procedure given by the block code encodes each message individually into a codeword, also called a block in the context of block codes.
