Abstract
k information bits are encoded according to a code with which is associated a parity check matrix H that has n columns. The entire resulting codeword is stored in a storage medium. At least n'<n bits of a representation of the codeword are read from the storage medium and an attempt is made to decode only the n′ bits using a matrix H′ that has fewer columns than H. Typically, H has m=n−k rows and H′ has m−(n−n′) rows and n′ columns. If the attempt fails, one or more additional bits are read from the storage medium, if necessary, and are combined with the n′ bits, and the decoding attempt is repeated using a matrix H′″ that has more columns than H′.
