signaldetection

this is a source code for contours detection.

循环谱计算程序,采用FAM平滑算法,画出了图形(spectrum of the signal cycle program,)

802.11的OFDM系统方针程序，比较全面详细。(802.11 OFDM systems approach procedures, more comprehensive details.)

对信号进行短时傅里叶变换，可以方便的调节各种短时傅里叶变换的影响因素。(Short-time Fourier transform of the signal, you can easily adjust a variety of short-time Fourier transform of the influencing factors.)

matlab程序用来解薛定谔方程，程序源代码说明详细，可直接使用(matlab program for solving schrodinger equation. there are detailed expression for using the code)

动画技术：电偶极子辐射的动态仿真,影片动画和实时动画。绘制各个时刻的电力线图，即使用contour函数在 t取不同值的情况下绘制电力线方程(Animation techniques: electric dipole radiation dynamic simulation, film animation and real-time animation. Rendering of each hour power line, which USES contour function in the wt take different values of electric draw equations )

维纳滤波语音增强算法:语音增强算法的维纳滤波器，通过scalart 1996提出的实现。使用一个决策指导的方法跟踪的先验信噪比。请注意，该信号的第一0.25sec用于模型的噪声，即，它是假定的演讲之后，0.25sec开始(Wiener Filter for Noisy Speech Enhancement, implemented as proposed by Scalart 1996. Uses a decision directed method to track the a priori SNR. Note that the first 0.25sec of the signal is used to model the noise, that is, it is assumed that speech starts after that 0.25sec)
