图像的FFT变换和DCT变换的MATLAB代码(Image FFT transform and DCT-MATLAB code)

CDMA 仿真程序 将txt改回m即可使用 主要是链路级的方针程序(CDMA simulation program will txt back to m is to use the principle of link-level procedures)

时频工具箱，以上给了很多函数，但常用的基本就是短时傅里叶变换STFT、Wigner-Ville分布WVD、伪Wigner-Ville分布PWVD和提取瘠ridges、得到理想时频表示tfrideal。(Time-frequency toolbox over to a lot of functions, but the basic is commonly used short-time Fourier transform STFT, Wigner-Ville distribution WVD, pseudo-Wigner-Ville distribution PWVD and extraction barren ridges, when you get the ideal frequency representation tfrideal.)

这个 matlab 代码仿真了M-QAM的传输。M的取值不同，调制方式分别为4QAM，16QAM，64QAM等。传输信道为AWGN信道，能出误码率曲线(Digital Unit Impulse Discrete Harmonic Signals and their Linear Combination Harmonic Signal with Exponential Envelope. Periodic Sequence of Rectangular Impulses Mixture of Harmonic Signal and White Gaussian)

说明：  用matlab代码编写的图像盲反卷积，可以实现较好地实现灰度图像的盲反卷积(Matlab code used to prepare the image blind deconvolution can be achieved to better achieve the gray image of the blind deconvolution)

说明：  用Matlab实现亚当姆斯法，用来进行控制系统的仿真。(Using Matlab to achieve Adams method, used for control system emulation.)

dicm2nii.m converts dicom files in a zip file or in a folder (including sub-folders) into nifti files. It can also convert Philips PAR/REC files and AFNI HEAD/BRIK files

The implementation was built on Matlab/Simulink using fundamental components in Simulink to demonstrate how reliably complex modulation schemes can be built, cost effectively and efficiently [5]. The design of ZigBee transmitter using MSK modulation is shown in the Figure 1. Here we map input data bits to 8-chip PN sequences to be transmitted and results in a chip rate of two mega chips per second. After that, resultant chip sequence is send to the serial to parallel converter. It is used here to separate the odd and even bit indexed chips. Following this bipolar data formatting is performed and signal modulated with a 2.4 GHz carrier on the In Phase and QuadraturePhase data stream and adds it to get the required transmitter output signal.
