说明：  基于嵌入式C语言，在ARM平台实现用于组合导航的卡尔曼滤波算法(include kalman_init();kalman();kalman_Q_R_H()....etc)

和放大器；

AD2S1210旋转变压器程序，能设计成16位编码器。同时能测量电机的转速(AD2S1210 resolver program)

说明：  基于StC89C52单片机的nRF24L01驱动及应用程序， 已经调试成功(Driver and application program of nRF24L01 based on STC89C52 MCU has been debugged successfully.)

主要用途是对抗多径衰落。由于多径衰落的存在，使得同一个帧由于路径不同，到达用户端的时延有先有后。在相关的频域上的会造成子载波之间的相互干扰，影响 性能。另外，由于有了循环前缀，使得IFFT FFT操作把原来的线性卷积变成循环卷积，大大简化了相应的信号处理复杂度(The main purpose is to fight against multipath fading. Due to the presence of multipath fading, the first after they have the same frame different paths to reach the client delay. Would cause mutual interference between sub-carriers in the frequency domain, affecting performance. In addition, thanks to the cyclic prefix, so IFFT FFT operation to the linear convolution of the original into a circular convolution, greatly simplifying the corresponding signal processing complexity)

SVM的C语言实现代码，可以直接移植到自己的工程中。(SVM' s C language code can be directly transplanted into their own works.)

基于LOD技术的3D海底地形仿真系统。主要讲述海底地形的绘制及仿真系统的组成。(Based on the LOD 3D seafloor topography simulation system. Focuses on the composition of the seabed topography mapping and simulation system.)
