基于IEEE802.11a物理层的硬件研究

Research on IEEE802.11a based on the Physical Layer Hardware

随着互联网应用的日益广泛,无线网络受到人们越来越多的关注。IEEE802.11a是当前应用最广泛的无线局域网标准。首先分析了IEEE802.11a的物理层,描述了其功能和汇聚过程,其次分析其系统的开发平台和系统工作流程,通过当前流行的DSP芯片和FPGA芯片相结合,利用C语言对其进行开发,最后给出了部分核心代码。该系统的研发,对于网络工作者和硬件开发人员都有着巨大的帮助。

with the wide application of Internet, more and more attention by the wireless network. IEEE802.11a is a wireless LAN standard is currently the most widely used. This paper first analyzes the physical layer of IEEE802.1 la, described the function and the convergence process, followed by analysis of working process of the system development platform and system, through the combination of DSP chip and FPGA chip are popular, in the development of the use of C language, some core codes are presented. The development of this system, are of great help for network operators and hardware developers.
