摘要： WiMAX下的编码方式是当今通讯技术研究的热门。介绍一种最受关注的纠错编码:低密度奇偶校验码 (Low Density Parity Check, LDPC)，讨论LDPC码在WiMAX条件下的基本原理和编译码设计;提出运用Visual 特点构建LDPC码仿真平台，研究仿真设计过程;分析不同实现方法下对LDPC码性能的影响，通过对仿真结果的分 析和思考，说明了Visual+语言应用于I_DPC编译码仿真的可行性、实用性和扩展性。
关键词: 低密度奇偶校验码，仿真，C语言，H矩阵，算法
Abstract: Encoding under WiMAX is a hot topic in today's telecommunication technology research. hhis paper intro- duced one of the most popular error correction encoding; Low Density Parity Check code (LDPC code)，discussed the basic principle and encoding-decoding design of LDPC code under WiMAX，put forward a LDPC code simulating plat- form by using Visual C++ characters, studied the procedure of simulation design, analyzed the impact to LDPC code performance under different realization method, and by analyzing and studying of simulation results, explained the feasi- bility, practicability and expansibility of Visual C++ applied in LPIX; encoding-decoding simulation.
Key words: LDPC, Simulation, C language, H matrix, Algorithm
