[Communication-MobileEXIT

Description: 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.

[Otherturbo_code_5g

Description: 5G通信必须用到的编码:Turbo码是Claude.Berrou等人在1993年首次提出的一种级联码。基本原理是编码器通过交织器把两个分量编码器进行并行级联,两个分量编码器分别输出相应的校验位比特;译码器在两个分量译码器之间进行迭代译码,分量译码器之间传递去掉正反馈的外信息,这样整个译码过程类似涡轮(Turbo)工作。因此,这个编码方法又被形象地称为Turbo码。Turbo码具有卓越的纠错性能,性能接近香农限,而且编译码的复杂度不高。-5G communication must be used in coding: Turbo code is a concatenated code Claude.Berrou et al in 1993 first proposed. The basic principle is that the encoder by interleaving the two components is parallel concatenated encoder, two component encoder outputs the parity bit bit decoder between the two components decoder iterative decoding, remove extrinsic information transfer between the positive feedback component decoder, so that the entire decoding process similar turbine (turbo) work. Thus, this coding method has been aptly called Turbo codes. Turbo codes have excellent error correction performance, performance close to the Shannon limit, and the complexity of the codec is not high.
