说明：  用粒子群算法计算最短路径，一般用于车辆路径问题(PSO)

这本书包含了很多Matlab编程的技巧，对初学者会有帮助。(This book contains a lot of Matlab programming skills would be helpful for beginners.)

A novel constant false alarm rate(CFAR)detection algorithm is proposed in this paper．The Biparameter CFAR detection is applicable tO Gaussian noise in non—coherent integration for radar dim target detection algorithm．The paper analyzed the probability of false alarm in theory．Monte—Carlo simulations demonstrate that the Biparameter CFAR processor has achieved about 5 dB SNR gains in detection performances comparable to the conventional cell—averaging CFAR processor．

用matlab进行概率密度函数的非参数估计，主要有parzen窗法和kn近邻法。分别对平均分布和正态分布进行了仿真。(Non-parametric estimation of the probability density function using matlab, main the parzen window method and kn nearest neighbor method. The average distribution and normal distribution were simulated.)

1. 设计一个 N = 10 的低通 fir 滤波器，对 fs = 8kHz 的信号 fc = 2.5kHz 2. 设计等同性能的 IIR 滤波器 3. 定点实现，不能使用浮点 4. 测试多正弦波合成文件 MultiToneTest.wav 分析输出结果 5. 测试语音文件 sc03.wav 得到输出结果(1. Design a lowpass fir filter N = 10, for fs = fc 8kHz signal design equivalent of = 2.5kHz 2. 3. IIR filter performance fixed-point implementation, you can not use floating-point multi-sine wave synthesis document 4. Testing 5. Test MultiToneTest.wav analysis output file sc03.wav get voice output)

横向各相同性介质的各个弹性系数，方便进一步计算其它弹性性质(the elastic properties of TI media)

关于认知无线电频谱感知的能量检测程序,很基础 适用于新手(Energy detection program for cognitive radio spectrum sensing.)

this file is an ac to ac controller. you can control the output by adjusting the firing angle of the SCR.

航空信道模型，包含直射路径和延迟路径，信息经过编码后进信道，经过滤波后输出(Air channel model, including direct path and delayed path, the information encoded backward channel, through the filtered output)

关于focus编程的相关学习资料，有详细的说明(Focus programming related learning materials, detailed instructions)
