I'm looking for a good book on BCH codes and decoding algorithms.
Specifically, I need an efficient decoder for a BCH(21,31) which
detects up to 4 errors and corrects up to 2.

FYI: this is the error correcting used in the POCSAG standard.

If you know of an algoithm or book, please send me some e-mail,
thanks,
jmar
