本科论文，有限元法求解对流扩散方程。文后有附带的程序，适合入门使用！可以对照文章内容，学习程序!(A paper for FEM.)

ofdm信道估计仿真（ls算法，mmse算法，还有一种改进的mmse算法lmmse，可以直接在马特拉并上运行）(OFDM channel estimation simulation (ls algorithm, mmse algorithm, as well as an improved MMSE algorithm lmmse, can be directly in the Matra and run))

GPS采集，GPS信息读取,内容很全，用C#开发的，适用于window mobile、window ce设备上使用。(GPS acquisition, GPS information is read, the content is very wide, with a C # development for window mobile, using the window ce device.)

说明：  FM（Frequency Modulation）即调频，习惯上用FM来指一般的调频广播（76-108MHz，在中国为87-108MHz、日本为76-90MHz），事实上FM也是一种调制方式，(FM (frequency modulation) refers to the general FM broadcasting (76-108mhz, 87-108mhz in China and 76-90mhz in Japan). In fact, FM is also a modulation mode,)

fvcom后处理程序，可利用matlab提取数据后对数据进行可视化处理(FVCOM post processor, which can be visualized after extracting data from MATLAB)

可以实现多相滤波数字信道化，可以自己改各种参数(Multiphase filtering can be digitally channelized, and various parameters can be modified by itself.)
