  • To enable the practicability of the low density parity check codes, a QCE-PEG algorithm is presented, followed by the description of the implementation approach and a design case in detail. The algorithm divides the construction into two processes, combining the Quasi-Cyclic Extension (QCE) method and Progressive Edge-Growth (PEG) technique. It has several advantages such as good degree distribution, long average girth, rapid encoding process and good performance. Simulation result shows that the constructed irregular LDPC codes have good performance, simple and practicable, thus creating good conditions for its wider application.
