说明：  非常好的数字处理教程，可以从中学到如利用matlab产生各种音频(Very good tutorial digital processing, can learn, such as the use of matlab have a variety of audio)

粒子滤波技术在非线性、非高斯系统表现出来的优越性，决定了它的应用范围非常广泛。另外，粒子滤波器的多模态处理能力，也是它应用广泛有原因之一。国际上，粒子滤波已被应用于各个领域。在经济学领域，它被应用在经济数据预测；在军事领域已经被应用于雷达跟踪空中飞行物，空对空、空对地的被动式跟踪；在交通管制领域它被应用在对车或人视频监控；它还用于机器人的全局定位。 (Particle filter technology in the non-linear, non-Gaussian system demonstrated the superiority of the decision of its wide range of applications. In addition, the particle filter for multimodal capabilities, also has one of the reasons it is widely used. Internationally, the particle filter has been applied to various fields. In economics, it is applied to forecast economic data in the military field have been applied to radar tracking aerial flying objects, air to air, air-passive tracking in the field of traffic control it was used in the car or the person video monitoring also used the global positioning robot.)

协作频谱感知虽然可提高系统的感知性能， 但随着感知节点数目的增加， 系统资源的占用越来越多， 系统传输效率下降． 分析了协作频谱感知方法的感知性能， 得到协作频谱感知的感知性能与感知节点数目和接 收信噪比之间的关系， 提出了一种新的次级用户节点的选择方法， 该方法有效保证了所选择节点的感知性能， 仿真验证了该算法的有效性和可靠性．(Although the cooperative spectrum sensing can improve the perceived performance of the system, but with the perception of the number of nodes increases, more and more system resources, the system transmission efficiency decreased. Cooperative spectrum sensing method of analysis of the perceived performance of collaborative spectrum sensing by the perception of performance and perception of the number of nodes and the relationship between the received SNR, a new secondary user node selection method, which effectively guarantee perceived performance of the selected node, the simulation proves the validity and reliability.)

说明：  基于LDA的人脸识别源代码，可以很方便的实现人脸识别(LDA-based face recognition source code, can easily realize face recognition)

通过用matlab程序设计实现IIR高通数字滤波器。(By using matlab program design of IIR high pass digital filter. )

code for de estimator....

Hilbert Huang Transform 绝对可用 性能超强哦:)(Hilbert Huang Transform absolute performance super available Oh:))

excellent plotting toll of signals

一般情况下，ellipse函数只能实现尺度较小的椭圆模拟，次程序实现长短轴较大且椭圆中心在任意象限情况下的椭圆模拟函数(for the semi-major and semi-minor ellipse simulation)
