一种Turbo码的编码算法仿真实现

The Emulational Realization of a Code Algorithm of Turbo

对Turbo码的编码的基本原理及编码中的关键元件和技术做了介绍,其中包括交织器的原理,最主要的是对Turbo码在CDMA2000中的编码进行了Matlab仿真,在Turbo码编码的设计仿真过程中对交织器和抽取器进行了算法的实现,模块的封装,计算结果与理论值较接近,有助于对Turbo码的进一步研究。

This paper introduces the basic principle of Turbo code and the key components and technologies including the principle of the interweaver with emphasis on the emulation of Turbo coding in the system of CDMA2000 by Matlab. During the procedure of design and emulation, the code algorithm about the interweaver and sampler is realized and the module is encapsulated. The emulation value approaches the theoretical value, which is helpful to further researches.
