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. WebIn fact, as we will see later in the section, the rate of BCH codes is optimal, up to lower order terms. BCH codes can be de ned over any eld, but for today’s lecture we will focus …
