Binary bch codes
WebThe BCH codes are binary block-codes while the Reed-Solomon codes are non-binary block-codes. The coefficient multiplication in the BCH encoder is a simple binary … Web6.1.2 Cyclic Codes. The most commonly used class of linear block codes is the cyclic codes. Examples of cyclic codes include BCH codes, Hamming codes, and Golay codes. RS codes are also cyclic but nonbinary codes. Even LDPC codes can be designed in cyclic or quasi-cyclic fashion.
