非常实用的工具，可以用Matlab来进行射频上船用的转换以及分析。（例如可以将S矩阵转化成Z矩阵，放大器稳定性分析……）...

GPS receive program,use AT89c51,displayed by 1602lcd.

此程序为GPS软件接收机的源码，能够对匹配滤波后数据实施捕获和跟踪算法，对理解GPS接收机原理有很大帮助。-procedure for the GPS receiver software source code, to the matched filter after the implementation of data capture and tracking algorithm, the GPS receiver understanding will be of great help.

基带测量信号处理的算法：1.最小二乘曲线拟合法2.线性滤波方法3.非线性滤波方法非线性滤波方法就是和深组合导航系统中利用联邦卡尔曼滤波的方法是一样的，基带信号处理相当于联邦卡尔曼滤波中的局部滤波器

MO中利用图片生成点符号专题　 deskfee 发表于 2005-3-15 14:34:24 用truetype字体可以比较方便的实现点符号，但用图片可以实现更加漂亮的点符号（如果你认为你做的图标足够漂亮的话，^_^），只是实现起来麻烦一点。 文件是txt,下载完后请先更改-MO use photographs to generate symbols deskfee topic published in 2005-3-15 14:34:24 truetype fonts can be used to facilitate the realization of more symbolic point, but pictures can be used to achieve a more beautiful symbol of the point (if you think you have done enough beautiful icon, ^ _ ^), but is only one point up trouble.
