The construction of fast, high-rate, soft decision block decoders
Elwyn R. Berlekamp · IEEE Transactions on Information Theory · 1983
A detailed description is given of a fast soft decision decoding procedure for high-rate block codes. The high speed is made possible (in part) by using the symmetries of the code to simplify the syndrome decoding by table look-up and by making the best use of the soft decision information. The(128,106,8)BCH code is used as an example.
