Alexis Hocquenghem, and independently in 1960 by Raj Bose and D. K. Ray-Chaudhuri.[1][2][3] The acronym BCH comprises bch error correction code tutorial the initials of these inventors' names. One of the key features

of BCH codes is that during code design, there is a precise control over the number of error detection and correction in computer networks symbol errors correctable by the code. In particular, it is possible to design binary BCH codes that can correct multiple bit errors. Another advantage of BCH codes is

the ease with which they can be decoded, namely, via an algebraic method known as syndrome decoding. This simplifies the design of the decoder for these codes, using small low-power electronic hardware. BCH codes are used in applications such as satellite communications,[4] compact disc players, DVDs, disk drives, solid-state drives[5] and two-dimensional bar codes.
