代码说明：

语音是人类交换信息的有效渠道之一，也是我们日常生活交流的主要形式。语音与当今科学技术的快速发展息息相关，特别是计算机中的语音交互技术，通过对语音信号进行采集和处理，实现人与人之间有效信息的传输、获取以及存储。基于 MATALAB 的语音信号去噪设计，对噪声信号进行有效地滤除，将降噪后的语音信号与原始信号在时域和频域进行对比分析，计算出信噪比，并在 MATLAB 中设计 GUI 仿真界面进行展示.(Speech is one of the effective ways for human to exchange information, and it is also the main form of our daily life communication. Speech is closely related to the rapid development of modern science and technology, especially the voice interaction technology in the computer. Through the acquisition and processing of voice signals, the transmission, acquisition and storage of effective information between people and people is realized. Based on the noise signal de-noising design of MATALAB, the noise signal is effectively filtered, the speech signal and the original signal after the noise reduction are compared and analyzed in the time domain and frequency domain, and the signal to noise ratio is calculated, and the GUI simulation interface is designed in the MATLAB.)

利用小波的对图像的分解和重构，然后对重构图像消噪，并比较消噪前后的图像。(the use of wavelet image decomposition and reconstruction, and then reconstructed image denoising, and compare the before and after denoising images.)

cskmeans
cskmeans 聚类算法的一种 1. 分裂法(partitioning methods)：给定一个有N个元组或者纪录的数据集，分裂法将构造K个分组，每一个分组就代表一个聚类，K<N。而且这K个分组满足下列条件：（1）每一个分组至少包含一个数据纪录；（2）每一个数据纪录属于且仅属于一个分组（注意：这个要求在某些模糊聚类算法中可以放宽）；对于给定的K，算法首先给出一个初始的分组方法，以后通过反复迭代的方法改变分组，使得每一次改进之后的分组方案都较前一次好，而所谓好的标准就是：同一分组中的记录越近越好，而不同分组中的纪录越远越好。使用这个基本思想的算法有：K-MEANS算法、K-MEDOIDS算法、CLARANS算法；()

gnss-sdr-master
In order to start using GNSS-SDR, you may want to populate ```gnss-sdr/data``` folder (or anywhere else on your system) with raw data files. By raw data we mean the output of a Radio Frequency front-end s Analog-to-Digital converter. GNSS-SDR needs signal samples already in baseband or in passband, at a suitable intemediate frequency (on the order of MHz). Prepare your configuration file, and then you are ready for running ```gnss-sdr config_file=your_configuration.conf```, and seeing how the file is processed.
