Digital Predistortion of Nonlieaner RF Power Amplifier with Memory Effects. This M code simulates a DPD technique linearization for a AB-class nonlinear HPA with memory effects. Here we consider a memory polynomial predistorter to modeling nonlinearity characteristics and memory effects of a HPA.Simulation procedures divided into three separate parts: 1)Analog imperfection compensation for the direct upconversion transmitter 2)Design a DPD based on a memory polynomial predistorter 3)Performance evaluation via a number of parameters such as:EVM,PSD,SNR,

Matlab 求声音信号的包络的源代码 使用方法见说明(Matlab for the sound signal envelope of the source code)

首先一个是基于JAKE模型的多径衰落信道模型及性能分析。另外一个是OFDM系统中基于上述信道模型的性能分析。(JAKE first model is based on a multipath fading channel model and performance analysis. Another system is the OFDM channel model based on the above analysis of the performance.)

利用球贝塞尔函数和汉克尔函数计算低频、中频、高频的雷达散射截面。(The calculation of the radar cross section of low frequency, intermediate frequency, high frequency by using the spherical Bessel function and Hankel function.)

说明：  用Matlab产生正弦波,矩形波,以及白噪声信号，并显示各自时域波形图 进行FFT变换，显示各自频谱图，其中采样率，频率、数据长度自选 做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱 用IFFT傅立叶反变换恢复信号，并显示恢复的正弦信号时域波形图(fft analysis,plot rms spectrum,power density spectrum, etc.)

按libsvm格式的数据录入，transform函数需要另外编写(Data entry by libsvm format, transform functions need to prepare the)

压缩文件里边包含好几个合成地震记录的程序，包括楔形模型，断层等，有的还画出了地震记录，反射系数的振幅谱~(the zip file contains several synthetic seismogram programs, including wedge model, fault model, etc., some even draw the earthquake records, the reflection coefficient of amplitude spectrum ~)

it has the programs of the matlab regrding the image processing, some matrix operation
