- Linear block codes have the property of linearity, i.e. the sum of any two codewords is also a code word, and they are applied to the source bits in blocks, hence the name linear block codes. There are block codes that are not linear, but it is difficult to prove that a code is a good one without this property.

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.
Algebraic coding theory is basically divided into two major types of codes: [citation needed] Linear block codes; Convolutional codes; It analyzes the following three properties of a code – mainly: [citation needed] Code word length; Total number of valid code words
Sep 23, 2012 · block code, highlighting the primary reason why linear (block) codes are attractive: the ability to decode them efficiently. We also discuss how to use a linear block code that works over relatively small block
Cite. Summary. In this chapter, we consider block codes with a certain structure, which are defined over alphabets that are fields. Specifically, these codes, which we call linear codes, form linear spaces over their alphabets. We associate two objects with these codes: a generator matrix and a parity-check matrix.
