现代通信系统matlab第五章基带数字传输源代码(Modern communications systems Chapter matlab source code baseband digital transmission)

用雷达散射中心模型对一维距离像进行计算的函数。(A function of generating a one-dimensional distance image a scattering center model)

Interactive smoothing for time-series

说明：  粒子滤波程序,对目标进行跟踪，附有状态方程和量测方程(PF)

Image Compression A collection of simple routines for image compression using different techniques. BTCODE: Image compression Using Block Truncation Coding. PYRAMID: Image compression based on Gaussian Pyramids. DCTCOMPR: Image compression based on Discrete Cosine Transform. IMCOMPR: Image compression based on Singular Value Decomposition. The given codes can be also used in 2D noise suppression. Notes: The function conv2fft performs a 2D FFT-based convolution. Type help conv2fft on MATLAB command window for more informations.

求变截面梁的模态，目前只支持一处变截面，可以自己修改尺寸数据，简单好用(mode shape of the stepped cantilever beam)

说明：  用LZW算法，扩展的ASKII码作为初始化字典的词条，即字典的0-255项预置为ASKII的全部8位字符，将文档压缩与解压缩(Using LZW algorithm, the extended askii code is used as the entry of initialization dictionary, that is, 0-255 items of dictionary are preset as all 8-bit characters of askii to compress the document)

Computer-generated "random" numbers are more properly referred to as pseudo random numbers. This report explains the process of generating pseudo random numbers by residue method

Amplitude modulation and demodulation

这是一个用matlab语音编写的完整的指纹识别程序，用matlab语言实现了识别指纹、比较两个指纹图像相似度等功能，并设计了用户界面，使用户方便地进行图片的提取和分析，同时直观地显示出比较结果，方便直观(This is a complete fingerprint recognition procedures written in a voice with matlab, matlab language used to identify fingerprints, similarity compare two fingerprint images and other functions, and design a user interface that allows users to easily extract and analyze images, while visually shows the comparison results, convenient and intuitive)
