用jacobi迭代方法来求解方程组的解的程序(With Jacobi iterative method to solve the solution of system program)

睫毛最优阈值化处理之后用基于连通域搜索的方法进行噪声点删除，主要用到函数bwareaopen，代码包含在jiemao.m文件中。(Optimal threshold eyelashes after treatment with the method based on connected local search to remove the noise points, mainly used in the function bwareaopen, the code contained in the jiemao.m file.)

此代码为多分辨率小波变换，可对原始信号进行多尺度分解(This code for multi-resolution wavelet transform, the original signal can be multi-scale decomposition)

参考3GPP相关标准并根据LTE技术特征和关键特性，对下行链路级进行设计，包含以下步骤：比特生成、CRC校验、码块分割、编码、速率匹配、码块级联、加扰、调制、层映射、预编码、资源映射、OFDM符号生成和天线映射。为模拟无线传输信道，还需仿真相应的信道模型。收端则是发端的严格逆过程，对接收信号进行一系列处理，得到代表原始发送的信息并判决。(References 3GPP LTE technology standards and in accordance with characteristics and key characteristics of the downlink stage design, comprising the steps of: generating bits, CRC checksum, code block segmentation, encoding, rate matching, code block concatenation, scrambling, modulation , layer mapping, precoding, resource mapping, OFDM symbol generation and antenna mapping. Analog wireless transmission channel, the need to emulate the corresponding channel model. The receiving end is the inverse of the originator of the rigorous, a series of processing the received signal, the representation of the original transmitted information and judgment.)

利用matlab m文件，实现了接收机ROC性能曲线的绘制(Use matlab m files, to achieve the performance of ROC curves plotted receiver)

图像分割技术 边缘分割技术 阈值分割技术 matlab代码(Image Segmentation Edge Segmentation Thresholding techniques matlabcode)

Real world problems often present multiple, frequently conflicting, objectives. The research for optimal solutions of multi-objective problems can be achieved through means of genetic algorithms, which are inspired by the natural process of evolution: an initial population of solutions is randomly generated, then pairs of solutions are selected and combined in order to create new solutions slightly different the initial solutions. The fittest solutions are kept in the population and are used to generate new solutions

matlab实现矩形脉冲和根升余弦脉冲的QPSK调制功率谱密度及不同信噪比信道下的星座图，直接运行main函数即可(Plot the power density spectrum of the transmitted signal (e.g., with the matlab function psd) with different pulse shapes. How is it affected if a root raised cosine pulse is chosen instead of a rectangular pulse shape? Study the signal constellation in the receiver for various values of Eb/N0 for the AWGN channel. )
