Binary Bose-Chaudhuri-Hocquenghem (BCH) codes [88, 89] are usually adopted in applications that have random bit errors and require lowcomplexity encoders and decoders. Examples of such applications are optical communications, digital video broadcasting, and Flash memories. This chapter presents the encoder and decoder architectures for binary BCH codes. Similar to Reed-Solomon ...
