Parity-check matrix

In coding theory, a parity-check matrix of a linear block code C is a matrix which describes the linear relations that the components of a codeword must satisfy. It can be used to decide whether a particular vector is a codeword and is also used in decoding algorithms. (Wikipedia).

Parity Check

Parity check is a simple method of checking for errors in a communications systems. I'm Mr. Woo and my channel is all about learning - I love doing it, and I love helping others to do it too. I guess that's why I became a teacher! I hope you get something out of these videos - I upload al

Error detection: Parity checking

Parity checking is a basic technique for detecting errors in data transmission. This video explains how it works and walks through building hardware to compute and check parity. The hardware is based on my previous video: https://youtu.be/eq5YpKHXJDM Code from this video: https://github.

Local Correctability of Expander Codes - Brett Hemenway

Brett Hemenway University of Pennsylvania April 14, 2014 An error-correcting code is called locally decodable if there exists a decoding algorithm that can recover any symbol of the message with high probability by reading only a small number of symbols of the corrupted codeword. There is

Ruud Pellikaan: The coset leader weight enumerator of the code of the twisted cubic

In general the computation of the weight enumerator of a code is hard and even harder so for the coset leader weight enumerator. Generalized Reed Solomon codes are MDS, so their weight enumerators are known and its formulas depend only on the length and the dimension of the code. The coset
