关于纠错码的很好的书籍。讲述了各种纠错码的原理(The error correcting code of good books. About the principle of a variety of error-correcting code)

A differential QPSK modem using the TMS320C6711 DSK

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.)

这是一篇基于循环延迟分集的分组预编码和空时频编码技术方面的典型文章(This is a cyclic delay diversity based on the group pre-coding and space-time-frequency coding technology, a typical article)

数字通信中的16QAM映射，采用格雷码编码，包括星座图的显示，简单明了清晰，由此可以退出64,128QAM的matlab编码(Digital communication 16QAM mapping, the use of Gray coding, including the constellation display, simple clear, it can be out of the 64,128 QAM matlab code)

是用于OFDM系统， 能有效地降低系统地PAPR，同时可利用伪随机序列来结合PTS减少计算地复杂性和冗余(Be suitable for OFDM system to reduce the PAPR. and to combine with the m sequence to reduce the complexity of PTS algorithm.)
