说明：  斗接收机基带信号的捕获算法研究与算法仿真(Bucket receiver baseband signal acquisition algorithm and Algorithm Simulation)

An iterative QuRecursive method (using q-recursive) to generate Zernike

认知无线电环境中，当认知用户处于低信噪比环境时，软判决与硬判决的对比发现此时软判决优于硬判决(In Cognitive radio environment, the cognitive users in low SNR environment, the contrast of the soft decision and hard decision to soft decision is better than hard decision)

使用邻域平均法、中值滤波法、K邻近平均法进行平滑。 利用Roberts梯度法、Sobel算子和拉普拉斯算子进行锐化，并比较结果。 (smooth and sharpen)

直接法，间接法，AR普 功率谱估计,其他的自己看文档就能明白了(Direct method, indirect method, AR & P power spectrum estimation, the other will be able to understand a document that looks at)

这个是matlab下的全部时频分析在信号处理中的代码(this is the whole of Matlab time-frequency analysis in signal processing code)

三种方法实现数字下变频：直接法、bessel插值、多相滤波等(three method of DDC)

for using this code need to use signal toolbox and general toolbox in your matlab Using Haar transform to compress the image (showing remaining coefficen of Thresholded Image) and then using Inverse 2D Haar transform and finding the SNR to see how well decompression works

说明：  基于MATLAB完成的神经网络源程序，因为此类程序较多，我也分不清是否与现有资源相同(MATLAB based on the completion of the neural network source code, because such procedures more, I also distinguish whether or not the same as with the existing resources)
