TECHNIQUE FOR MULTIPLE ACCESSING

针对OFDM系统，分成链路级仿真和系统级仿真两个部分。为了降低系统级仿真的复杂度，采用链路级仿真的部分结果。(It contains mainly two parts, i.e. link-level simulator and system-level simulator. Link-level simulator focus on a single-cell single-user scenario, where signal is transmitted from tx, and estimated at rx. Comparing the difference in tx/rx signal, the error rate can be found out. The output of the link-level simulator is the BLER/BER vs. SNR mapping table, that can be used for the system-level simulation. System-level simulator focus on a multi-cell multi-user scenario. For the sake of simplicity, it takes the mapping table aquired in the link-level simulation, measure the actural SNR, and finds the corresponding error rate. Link-level simulator support SISO, 1 by x MRC, 2 by 1 STBC/SFBC, 2 by 2 Alamouti, x by 1 Antenna selection, x by y antenna selection. System-level simulator, currently support only SISO and 1 by 2 MRC. To start with, go into the folder sys_link_simu, and excute the following commond from matlab: sys_link_simu_func(a,b) where a is the link ada)

将图像分为nxn的分块,之后将各分块三个颜色通道的直方图平均化,最后进行离散余弦变化,分别提取各通道低频系数(The image into nxn sub-block after block of all three color channels of the histogram equalization, and finally the discrete cosine change, were extracted from the low frequency coefficients of each channel)

Dear Sir, I have uploaded some neural network and DSP kind of programms. Thank You, -bibyut
