仿真GPS接收机中的锁频环功能，与硬件设计十分相似，稍作改动即可实现锁相环功能(Simulation of GPS receiver in frequency-locked loop functions, and hardware design is very similar, minor modifications to achieve phase-locked loop function)

these are some papers on dstatcom

Astar algorithm for path finding

加窗设计FIR滤波器，其中有矩形窗和哈明窗两种窗的加窗方法及频谱分析(Windowed FIR filter design, including rectangular window and Hamming window of Windows and both methods and spectral analysis)

说明：  自适应滤波器原理(中文第四版) 介绍数字滤波器(Adaptive Filter Theory (fourth edition in Chinese))

Compute and minimise the PAPR of an OFDM channel

计算阶次分析的案例，需要转速信号进行角度域重采样。(In the case of order analysis, the angle domain resampling of speed signal is needed.)

测绘工程中常用的坐标转换代码，有WGS-xyz坐标系转经纬度、ENU坐标，有北天东坐标系转WGS-xyz、经纬度等(MAPPING commonly used coordinate transformation code, WGS-xyz coordinate system of latitude and longitude turn, ENU coordinate with the northern east coordinates turn WGS-xyz, latitude and longitude)
