摘要 对提高基于Matlab平台的低密度奇偶校验码的仿真速度进行了研究,为加快仿真速度,编解码核心过程用符合mexFunction格式的C语言编写,并针对快速编码算法及迭代译码算法进行了优化,然后编译成动态链接库文件在M语言中调用。仿真结果表明,优化后的仿真速度相比优化前获得大幅提高,平均提升了57倍。 Accelerating LDPC codec simulation on Matlab platform is studied.In order to make the simulation run faster,the core process of coding and decoding uses C language that conform to mexFunction format,both fast coding algorithm and iterative decoding algorithm are optimized,then compiles into a dynamic-link library file in M language.The simulation result proves that the simulation speed runs 57 times faster than the one without optimization.
