The topic, modeling process and the use of )

文件给出了matlab环境下的低通滤波仿真，并对每句话进行了分析(File under given matlab simulation of low-pass filter, and analyze every word)

基带传输： 欲传送的01比特流 + 码型变换（HDB3码） + 基带成型网络（采用升余弦滚降系统）+ 信道 + 码型反变换 + 01比特流。 (Baseband transmission: To send the 01 bit stream+ code type transformation (HDB3 code)+ base-band forming network (with raised cosine roll-off system)++ code based channel inverse transform+ 01 bit stream.)

基于四阶累积量特征分解的空间谱估计测向方法（信号处理的论文算法仿真 未找到分类）(Based on the fourth-order cumulant eigen-decomposition to the spatial spectrum estimation method (the paper algorithm simulation of the signal processing is not found Category))

经典的单类相关向量机程序，比较实用，适合初学者(classical one-class SVM program，very practical and satisfied for the beginner)

说明：  用MATLAB实现的S变换函数，具有FFT和小波变换的特性，是信号时频分析的有力工具，希望对大家有帮助。(Using MATLAB S-transform function, with the characteristics of FFT and Wavelet Transform is a powerful tool when the signal frequency analysis, we want to help.)

qpsk matlab仿真 F2T 傅里叶反傅里叶变换(qpsk matlab simulation)

计算杂波功率谱三维图形的程序，利用matlab平台开发(Clutter power spectrum calculation of three-dimensional graphics program, using matlab platform)

ofdm程序，关于信道估计算法的matlab程序(OFDM procedures, on the channel estimation algorithm matlab program)

说明：  本书旨在介绍小波变换，福利叶变换基本理论。小波变换在工程应用中很广泛，比如信号处理，图像处理等。(This book aims to introduce the wavelet transform, the basic theory of Fourier transform welfare. Wavelet transform in a very wide range of engineering applications, such as signal processing, image processing.)
