我做的关于数字信号处理的matlab实验。主要是卷积运算的实现和滤波器设计。(I have done on the digital signal processing matlab experiment. Is mainly the realization of convolution and filter design.)

说明：  根据语音信号的特点给出有关滤波器的性能指标：1）低通滤波器性能指标，fp=1000Hz，fc=1200 Hz， As=100dB，Ap=1dB；2）高通滤波器性能指标，fc=2800 Hz，fp=3000 Hz As=100dB，Ap=1dB；3）带通滤波器性能指标，fp1=1200 Hz，fp2=3000 Hz，fc1=1000 Hz，fc2=3200 Hz，As=100dB，Ap=1dB。用IIR对其分析，最后，利用MATLAB中的函数freqz画出各滤波器的频率响应。(This article according to the IIR filter and the FIR filter characteristic, uses the bilinearity method of transformation under the MATLAB bad boundary to design IIR and to design the FIR numeral filter separately with the window box number, and carries on the analysis to the gathering pronunciation signal, and finally gives IIR and FIR to the pronunciation filter effect.)

通过极坐标变换获得图像的中心投影曲线，然后利用傅里叶变换获得图像的不变特征，从而实现对发生形变的物体的识别。(Polar coordinates to obtain the image through the center of projection curve, and then Fourier transform to obtain images of the same features, enabling the identification of objects deformation occurred.)

扩频通信的相关仿真文件，希望有帮助，：）(Spread Spectrum Communication Simulation related documents, hoping to help :))

卡尔曼滤波的一种实现，VB，值得借鉴。该算法是用于处理实时数据的一种算法。(An implementation of Calman filter, VB, is worth learning from. The algorithm is an algorithm for real time data processing.)

求函数最大值，可用于一元和二元函数，采用鱼群算法计算(Maximum demand function can be used for unary and binary functions, using fish algorithm)

利用matlab图像处理计算一维信号的盒维数(Calculated using matlab image processing one-dimensional signal box dimension)

matlab的滤波方法有很多，该包中几何了中指滤波，维纳滤波，领域平均法滤波。(matlab has a lot of the filtering method, the package geometry of the middle filtering, Wiener filtering, average filtering fields.)

插值与拟合的matlab文件，插值与拟合在matlab中有很广的应用(Interpolation and fitting matlab files, interpolation and fitting in at matlab has a very wide application)
