Description

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Hadamard code, named after Jacques Hadamard, is a system used for signal error detection and correction. It is one of the family of [2n, n + 1, 2n ¿ 1] codes. Especially for large n it has a poor rate but it is capable of correcting many errors. Hadamard codes can be considered as a special case of Reed-Muller codes. In particular, first order Reed-Muller code are equivalent to Hadamard codes.The code is based on Hadamard matrices. If H is a Hadamard matrix of order 2n the codewords are constructed by taking the rows of H and ¿H as codewords, where each ¿1 is replaced by 0. In this way 2n + 1 code words are constructed that each have a length of 2n. Since the rows of a Hadamard matrix are orthogonal the minimum distance is 2n - 1. In this way a [2n, n + 1, 2n ¿ 1] code is constructed.
