Encoding method to QC code

摘要

In an encoding and/or decoding method utilizing a self-orthogonal Quasi-Cyclic (QC) code whose parity check matrix is expressed by at least one circulant matrix, a code sequence is generated which satisfies a check matrix. The check matrix is designed so that a column weight w of each circulant matrix is three or larger and a minimum hamming distance of the code is w+2 or larger.
