一种Turbo码的编码算法在CDMA2000系统中的仿真实现

The Simulation of a Code Algorithm of Turbo in CDMA2000

对Turbo码的编码的基本原理和对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。

In this paper the basic principles of Turbo code are mainly introduced, and the key components and technologies that include the principles of interweaver also introduced. The most important introduction is the simulation of Turbo coding in system of CDMA2000 by MATLAB. During the procedure of design and simulation, the code algorithm about interweaver and sampler are realized, and the module is encapsulated. As a conclusion, there is a difference between the simulation value and the theoretical value, which is helpful to the further research.
