基于OFDM技术的高速有线传输系统软硬件设计

摘要

It designed a high-speed wired transmission system based on OFDM technique.It consists of transmitter and receiver components,each of which contains the PC,DSP,Modem.Software system includes PC software and DSP software.PC software is responsible for human-computer interaction.DSP software is mainly responsible for data processing and transmission.Software system using the transmitter and receiver integrated design method.Software design uses the hierarchical design and modular design ideas,with good reusability and portability.It combines the use of web development,DSP,PC-programming and other techniques.Experimental results show that the system realizes high-speed and reliable data-transmission,has a good prospect.%设计了一种基于OFDM技术的高速有线传输系统,分为接收端和发送端两部分,每一部分均由PC、DSP、调制解调模块组成。软件系统由PC端软件和DSP端软件组成,其中PC端软件负责人机交互,DSP端软件主要负责数据的处理和传输,软件设计采用发送端和接收端一体化设计,使用了分层设计和模块化设计的思想,具有良好的复用性和移植性,综合使用了网络开发、DSP、PC编程等技术。系统实验结果表明,该系统能实现数据在双绞线上的高速、可靠传输,拥有良好的应用前景。
