摘要
首先分析了伪随机交织器在Turbo码中的重要作用,讨论了交织器的设计准则,给出了一种采用m序列的伪随机交织器的硬件电路实现方案。设计中利用Matlab平台上的DSP Builder工具实现伪随机算法,并基于开发软件QuartusⅡ进行了程序设计、功能仿真和综合。该交织器具有易于实现、占用硬件资源少、适应数据可靠性传输等优点。
This paper first analyzes the important role of pseudo-random interleaver in Turbo code, discusses the implementation of pseudo random interleaver based on m-sequence. The pseudo-random algorithms is achieved by using Matlab DSP Builder tool, and the program design, function simulation and integration are carried out by using Quartus Ⅱ tool. This pseudo-random interleaver is easy in implementation, occupies less hardware resources, and satisfies to the reliability requirement of data transmission, etc.
