周立功的LPC214x固件程序，很有用哈

MEMS陀螺随机误差建模算法研究。MEMS陀螺精度较低，随机漂移较大，严重影响系统的性能。对MEMS陀螺随机误差进行了时间序列分析，并建立了ARMA模型。使用MATLAB计算所选模型参数建立随机误差的系统方程，采用经典卡尔曼滤波器验证了在静态条件下，滤波后的信号标准差为滤波前的3．88％。针对动态条件下，常规卡尔曼滤波器滤波效果下降的问题，推导并设计了渐消卡尔曼滤波器。仿真结果表明，渐消卡尔曼滤波器能显著改善动态条件下的滤波效果，并且滤波精度较高。

还很好 -also very, very good very, very good

这个程序可以计算给定点处的小区信号范围覆盖。-is program computes a map of visibility from a selected point on a topography. It has been written to help the search for radio relay best location. Because it considers only direct line of sight, it gives a good estimation for possible radio link for short distances only (less than 10 km), neglecting curvature of the Earth, Fresnel zone and atmospheric refraction on radio waves propagation. The program computes the relative elevation angle of the mask for each point (the angle is null or negative if the point is visible). The function needs a digital elevation model Z and associated (X,Y) vectors or matrices of coordinates (same unit as Z), position of the point (X0,Y0), the antenna height H0 (for instance 4 m), and the hypothetic antenna height Ha on each topography points (for instance 3 m). When no output argument is given, the function plots a map of the results (color map of mask angles, and blank for visible points, see example screenshot). The s

实现（7，4）CRC的编码和译码，其中生成多项式可以在程序中改成所需要的。输入4位码，可以编码生成7位循环码。译码的情况限于至多错一位的情形。-To achieve (7,4) cyclic code encoding and decoding, which generate the polynomials can be changed in the program need. Enter 4 yards, you can generate 7-bit cyclic code encoding. Limited to a maximum of decoding a wrong situation.
