Abstract

The subject technology provides a decoding solution that supports multiple choices of code rates. A decoder may be configured to receive a selected code rate from a plurality of code rates. On the selection of the code rate, the decoder may determine a circulant size based on the code rate, and, on receiving the codeword, update, during one or more parity-check operations, a number of confidence values proportional to the circulant size in each of a plurality of memory units, each number of confidence values corresponding to a portion of the codeword.
