此仿真程序是目前论坛里面最完整的仿真源码，并且经本人调试运行，完全没有错误，有很高的研究价值。为各位搞仿真和做OFDM系统相关论文的研究生，而没有全面仿真程序的人提供本程序。此程序包含52个仿真模块，可以仿真出52个仿真图。-This simulation program is the forum inside the most complete source of emulation and debugging, as I run, there is no error, has high research value. For you to do engage in OFDM system simulation and related post-graduate theses, and no comprehensive simulation program provide the program. This program contains 52 simulation module can be a simulation simulation Figure 52.

应用背景以太网交换机所使用的以太网控制专用芯片多具有SMI接口,以实现对芯片的控制。考虑到以太网交换机的节能趋势,使用ARM芯片s3c2440作为以太网专用芯片的主控器件,使用软硬结合的方法,设计并实现了单片机系统与SMI接口的通信,介绍了SMI接口的特征和时序,并以以太网控制芯片88E6097为例,给出了在ARM芯片s3c2440上用I/O实现SMI接口的硬件电路和相关程序。关键技术基于c语言的SMI接口模拟，88E6097交换芯片的寄存器读写访问，88E6097芯片VLAN技术。采用ARM芯片s3c2440基于Linux的操作系统，通过c语言编程模拟SMI接口，对88E6097交换芯片的寄存器进行读取、写等操作，以达到对88E6097交换芯片基于802.1Q的VLAN配置。

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.
