通过simulink仿真工具架构的SCPC通信系统，基本架构为卫星通信系统，包括PCM编译码器、调制器、成型滤波、变频器、低噪声功率放大器、各类天线、模拟自由空间损耗、模拟等效噪声温度、卷积编译码器(The basic architecture of SCPC communication system based on Simulink simulation tool is satellite communication system, including PCM compiler, modulator, shaping filter, frequency converter, low noise power amplifier, all kinds of antennas, analog free space loss, analog equivalent noise temperature, convolutional compiling code.)

自己做的CRC16校验例子，输入16进制数据，数据之间用空格，得到校验字节(The CRC16 checksum own example, enter the hexadecimal data, with a space between the data check byte)

this is a code that shows QAM consetellation with data repetition (3 time repetition) the transmitted signal goes through flat fading Rayleigh channel

c-c算法可计算关联维数，延迟时间，嵌入维数等，对混沌分析有很大的意义(The C-C algorithm can calculate correlation dimension, delay time, embedding dimension and so on, which is of great significance for chaos analysis.)

Labwindows CVI 中不错的串口编程，串口调试(Good serial programming Labwindows CVI, serial debugging )

进行信号积累时，有的信号存在多普勒频率，不利于累加。该程序可完成对信号多谱勒频率的补偿。(Signal accumulation, some signal Doppler frequency, is not conducive to the accumulation. The program can be complete compensation of the signal Doppler frequency.)

这是一个用VC编写的MSCOMM控件的注册安装示例工程源代码，对于单片机的上位机软件开发是一个不错的小工具(This is a prepared using VC control register MSCOMM sample project to install the source code for the MCU PC software development is a good gadget)

实现相控阵雷达天线波束的形成，可以清楚地看到随相位变化的波形能量分布。(To achieve the formation of phased array radar antenna beam, we can clearly see the waveform energy distribution with phase change.)

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.)
