transfer function of a system

这是一篇关于学习matlab的课件，比较详细的课件，拿来共享一下(This is an article on the matlab learning courseware, a more detailed courseware, you used to share)

This code applies global histogram equalization on an input image with a view to improve its contrast ratio. The image is read, converted to grayscale and resized with the inbuilt function of MATLAB. The output is definitely a better contrast image as compared to the input

代码实现了最小均方差和迫零均衡器的误码率仿真图，并且通过对比理论曲线，验证了代码的正确性。(Code implements the MMSE and zero forcing equalizer BER simulation diagram, and by comparing the theoretical curves to verify the correctness of the code.)

卷积码编码与Viterbi译码的MATLAB仿真研究(Convolutional coding and Viterbi decoding of the MATLAB simulation)

Theory and implementation of Gaussian Random vector

freCBF程序，利用波束形成判定目标方位，产生某一方位角度的发射信号，利用波束形成判定目标方位(freCBF procedures, the use of beamforming determine the target bearing to produce a transmitted signal of the azimuth angle beamforming determine target orientation)

计算一维和二维卷积,基本可以替代Matlab中的conv和conv2函数,程序很方便就可以移植成C语言..(Calculation of one-dimensional and two-dimensional convolution, the basic alternative to Matlab' s conv and conv2 function, the procedure can be easily transplanted into a C language ..)

发送端统一使用4根发送天线,通过改变接收天线的数目来比较不同数目的接收天线对空间调制（spatial modulation）系统性能的影响。(Sending uniform use of four transmission antennas, by changing the number of reception antennas to compare the different number of receiving antennas for spatial modulation (spatial modulation) system performance.)
