IEEE802.11aOFDM基带仿真的Visual C++实现

Implementation of IEEE802.11a OFDM baseband simulation on the Visual C++ platform

针对OFDM系统复杂度高、仿真速度慢、程序可移植性差等问题,参考IEEE802.11a协议,对OFDM基带处理算法进行了研究,完成了基于Visual C++6.0平台的OFDM基带系统仿真软件.对软件的可靠性、可扩充性、可移植性进行了分析,并改进了部分算法对系统进行了优化,从而减少了大量的数据处理,运行效率提高了大约70%.

In order to solve the problems of OFDM system, such as its high complexity, slow computing speed and poor portability, we made a research on OFDM baseband processing algorithm on the basis of IEEE802.11 a Standard of Wireless Local Area Networks. Then, on the Visual C ＋ ＋ 6.0 platform, we developed a simulation software for baseband computation of OFDM system. At last, we gave an analysis on its reliability, expansibility and portability, and we performed the systematic optimization by improving part of the algorithm, thus reducing the amount of data process and improving the efficiency by 70 percent.
