摘要
介绍了CDMA2000系统中Turbo码的编码原理和通过MATLAB实现编码仿真的关键元件和技术-交织器、抽样器以及交织器的实现过程。仿真结果表明,可以用数据输出长度来衡量编码器的有效性。
The emphasis of this paper is the simulation implementation of the coding of Turbo by MATLAB in CDMA2000. Firstly, the principle of Turbo coding in the system of CDMA2000 is simply introduced; then the key components and technology-interleaver, sampler and the implementation procedures of interleaver are presented in detail. Lastly, the simulation using MATLAB validates the coding signal and proves that the validity of Turbo code can be evaluated by the length of code.
