基于小波变换的电力系统谐波检测与分析研究(Power system harmonic wavelet-based detection and analysis)

Matching Pursuit 算法是信号分解的一种具体实现方法。但其本质上则是一种估计 信号模型参数的方法，因而可直接用于信号检测及参量估计。本文以谐波信号特征参量的估计为例，介绍了其具体实现方法。(Matching Pursuit algorithm is a specific method of signal decomposition. But by its very nature is an estimated signal model parameters, and thus can be directly used for signal detection and parameter estimation. In this paper the harmonic signal characteristics of the estimates of the parameters, for example, describes the specific implementation method.)

说明：  该项目用于通过使用导频序列（训练序列）和信道抽头来估计OFDM中存在的信道。使用BER曲线比较系统的性能，该BER曲线是针对均匀间隔的飞行员和紧密间隔的飞行员获得的。此外，通道抽头的数量也有所不同，以估算最佳的BER曲线(This project is used to estimate the channel in OFDM by using pilot sequence (training sequence) and channel tap. The BER curve is used to compare the performance of the system, which is obtained for pilots with uniform interval and pilots with tight interval. In addition, the number of channel taps varies to estimate the best BER curve)

物理光学方法 近似计算散射体RCS POFACETS is an implementation of the physical optics approximation for predicting the radar cross section (RCS) of complex objects. It utilizes the scientific computational features of MATLAB and its Graphical User Interface (GUI) functions to provide an error-free encoding of input parameters and efficient calculation of RCS. POFACETS provides a convenient tool for a “first cut” at the RCS of complex shapes by representing its constituent parts by triangular facets. The software calculates the monostatic or bistatic RCS of the object for the parameters specified(POFACETS is an implementation of the physical optics approximation for predicting the radar cross section (RCS) of complex objects.
