代码说明:

说明:  傅立叶变换是一种线性的积分变换,作用是把信号在时域(或空域)和频域之间变换(Fourier transform is a linear integral transform, which is used to transform signals between time domain (or space domain) and frequency domain.)

  • EXIT
    本源码包参考英国Southampton大学Robert G. Maunder教授2008年的EXIT charts开源demo,给出了通用(分量码多项式可自定义)并行级联Turbo码的EXIT charts的作图源码。同时可完成迭代轨线、BER等值线的绘制等工作。 由于对于码块长较大的情形仿真需要较长时间,源码包也给出了部分分量码多项式的仿真结果,可直接用于绘图。 源码包还给出了最经典的S.Ten Brink介绍EXIT charts基本原理的参考文献,以及本人对通信系统中迭代译码过程分析技术综述的小论文,希望对大家有所帮助。(This source package comes after Professor Robert G. Maunder s open source demo about EXIT charts in 2008 from University Southampton, UK. It is designed for universal (constituent code generation polynomial can be customized) Parallel Concatenated Turbo Code EXIT charts. The iterative trajectories and BER contour drawing is also completed in this package. Since the long block case costs a lot of simulation time, some simulation results are included in the package. We also give the most classical introduction to the basic principles of EXIT charts from S. Ten Brink, as well as a document about analysis technologies for iterative decoding process in communication systems. Hope this will help.)

    是信号处理方面欠采样的源程序 ,是很不错的程序,可以这方面的学者一些参考价值(signal processing is owed sampling of the source, is a very good procedure, which some scholars regard the reference value)
