3-8译码器，可以讲三位二进制输入转换为8中取1的输出信号(3-8 decoder, you can talk about the three binary input is converted to 8 of the output signal from 1)

matlab下编写的三步快速搜索法，希望大家有用(Three Step Search Algorithm)

采用时频聚集性较好的线性调频信号作为线性时不变系统输入激励，采用Gabor字典作为过完备原子库。在利用传统系统辨识法之前先利用稀疏分解算法将输出信号进行去噪处理，显著提高系统辨识精度。 具体包括互谱算法，信号的Gabor稀疏分解的详细代码(Space can be a time for sparse decomposition to solve the problem of huge memory needed。This approach, combined with the rapid decomposition of FFT for signal ,so as to achieve satisfactory results.)

The DSI method is basically a modified SLM method. The additional aspect of the DSI method is to add M-bits dummy sequences to the original sequence in order to reduce the PAPR. Where, the dummy bits are inserted at the end of the data sequence (y). Next, after IFFT, we select the M-DSI sequence having the lowest PAPR.

Turbo Receiver Design for Phase Noise Mitigation in OFDM Systems

A simple code for selective mapping

复杂网络随机图生成，并生成邻接矩阵。运用MATLAB实现。(The random graph of complex network is generated and the adjacency matrix is generated.)

dehzing是总的代码，此代码包括 (1)dark channel(暗通道先验规律。首先是获取图像，然后得到一张与原图一样大小的灰度图，接下来就是对暗通道先验的转换代码。就先取每个像素的最小值，然后再取每个窗口的最小值。 (2)  guided filter（这里面包括box filter。这个滤波主要用来细化暗通道先验中的透射率t（x），其中导向图是I，p指预估透射率t（x），然后就是guided filter那片论文中的第7/8/9公式翻译为代码，即可）.

sar成像最后如果要查看结果，就是这个程序实现的功能，画出峰值旁瓣比！(sar imaging Finally if you want to see the results, is the function of this program, draw peak sidelobe ratio!)

QAM，(正交振幅键控调制)，输出为QAM调制产生的复包络信号(QAM, (quadrature amplitude modulation keying), QAM modulation output generated by complex envelope signal)
