通信系统仿真原理与无线应用代码…

这个文档主要是介绍GSM协议的内容，是官方的03。38版本。-this document is to introduce the main GSM the contents of the agreement, is the official 03. 38 version.

FPGA/CPLD应用,uart的Verilog HDL原码-FPGA/CPLD applications, UART Verilog HDL source

LabView 用于串口读写数据读取缓冲的最佳时间间隔，在串口通信内容长度不确定的情况下，能完整接收数据并在接收结束之后尽快的停止接收，决定串口通信的效率。此vi经过小修改应该就能普遍适用。

modbus总线协议 非常常用的工业总线控制协议-modbus connection bus protocol is used in industrial control protocol Bus!

通过仿真,分析了多径效应和多普勒效应的原理.并给出了移动信道的建模方案和程序.每个结论都给出了仿真程序可直接运行.-through simulation, Analysis of the multi-path effects and the principle of Doppler effect. and gives the mobile channel modeling programs and procedures. Conclusion gave each a simulation program can run.

this a matlab program for M array PSK modulation-this is a matlab program for M array PSK modulation

详细的介绍了MODBUS的协议内容 包括传输格式，功能码介绍等-introduce the MODBUS protocol in detail including translation style ,function code etc.

MATLAB程序的仿真比较。随后，针对QPsK，详细讨论了其基本原理和具体的实现算法，并进行了仿真验证，然后选用HSP502巧数字上变频芯片和HSP50214B数字下变频芯片，设计了数字调制、解调器的实现方案。最后，作为对整个数字视频图像传输系统的宏观认识，利用M户JLAB中的实时建模仿真Simullnk库对典型的视频图像传输系统一数字视频广播系统(D vB)，进行了建模、仿真和初步的分析，结果表明:在高斯白噪声的传输环境下，系统采取的一系列抗干扰措施，包括内、外码级联的信道纠错编码和先进的调制技术(o FDM)等，保证了信源信息传输的有效进行。-MATLAB simulation comparison. Then, against QPsK to discuss in detail the basic principles and specific algorithm, a simulation test, and then choose the cleverest HSP502 figures HSP50214B frequency chips and digital down conversion chips, the design of digital modulation, demodulation for the realization of the program.MJLABSimullnk(D vB):Andean white noise transmission environment, the system adopted a series of anti-jamming measures, including internal and external codes Cascade Channel advanced error correction coding and modulation techniques (o FDM), ensuring a source of information for the effective transmission.
