关于雷达系统仿真和分析，完整代码，值得学习(On the radar system simulation and analysis, the complete code, it is worth learning)

内容为matlabsimulink通信系统仿真配套例程， 有大量例程(this is example of communation program for matlab simulink)

说明：  功率谱估计编程，可以进行时域频域的转换，并提取频率、振幅、功率谱密度等相关参数(The power spectrum estimation program can transform the time domain and frequency domain and extract the related parameters such as frequency, amplitude and power spectrum density)

very useful robust control codes in matlab.

This paper propose a Firefly algorithm (FA) for optimal placement and sizing of distributed generation (DG) in radial distribution system to minimize the total real power losses and to improve the voltage profile. FA is a metaheuristic algorithm which is inspired by the flashing behavior of fireflies. The primary purpose of firefly’s flash is to act as a signal system to attract other fireflies. Metaheuristic algorithms are widely recognized as one of the most practical approaches for hard optimization problems. The most attractive feature of a metaheuristic is that its application requires no special knowledge on the optimization problem. In this paper, IEEE 33- bus distribution test system is used to show the effectiveness of the FA. Comparison with Shuffled Frog Leaping Algorithm (SFLA) is also given.

用Remez算法设计一个低通滤波器；设计一个5路5:1多相减采样滤波器和一个4路1:4多相增采样滤波器。(Remez algorithm with a low-pass filter designed by a 5-way multi-phase sampling filter and 5:1 4 1:4 a multi-phase sampling filter increases.)

matlab programing for engineers etc.

说明：  帮助matlab载入.sif文件，从而读取并处理文件内容(Help matlab load. SIF file to read and process file content)

说明：  特征值的提取方式 有需要的可以下载试试 还不错(for the value )
