METHOD FOR CONSTRUCTING LDPC CODE IN THE MOBILE DIGITAL MULTIMEDIA BROADCAST SYSTEM

摘要

A method for constructing LDPC (Low-Density Parity-Check) code in the mobile digital multimedia broadcast system is provided, wherein the Low-Density Parity-Check matrix of the LDPC code is iteratively constructed according to a code-table and extended method, and the code-table is part of the constructed Low-Density Parity-Check matrix. According to the constructing method of the present invention, LDPC code having good performance of error correcting coding is provided to the mobile digital multimedia broadcast system.
