在RGB、HSV、YCBCR空间提取得到了高质量的印章，算法鲁棒性很强。(the seal is well recognized in the space of RGB、HSV and YCBCR,and the method is robust.)

RSSI是无线传感器网络中一种基于测距的定位方法，本程序中使用对数常态模型来测距离。(RSSI is a wireless sensor network positioning method based on distance, this program is measured with a lognormal model for the distance.)

提供了四种不同的采集数据，001和002是FSK2信号，003和004文件是FSK4信号，两个mat文件是广播接收FM信号和对讲机接收的FM信号，这两个文件都是基带信号，其他六个都是中频信号，载波分别是250KHz（001-004文件）和21.6MHz（AM信号abc0和abc1文件），提供这几个采集到的数据文件供大家进行程序的测试和修正(Provides four different data acquisition, 001. 002 is a the FSK2 signal, 003 and 004 file is FSK4 signal, two mat file is the FM signal received by the broadcast receiving FM signals and intercom, these two files are a baseband signal, the other six are intermediate frequency signals, the carrier is 250KHz (001-004 files) and 21.6MHz (AM signal abc0 and the abc1 files), the provision of several data files collected for program testing and remediation)

一种基于几何均值分解的混合预编码技术研究(Hybrid precoding based on geometric mean decomposition)

This program describes the use of Inverse Synthetic Aperture Radar (ISAR) with stepped-frequency waveform (SFWF) to produce a high-resolution, 2D image of a target.

VOICE UNVOICED SILENCE PITCH MARKING

代码实现了二阶AR模型的最优权值递推，使用了LMS和RLS两种方法，对二者性能进行了比较，分别进行了单次和100次平均进行性能观察，并且仿真了不同步长因子对LMS算法的影响以及不同lamda值对RLS算法的影响。文档包含了模型的详细介绍以及2种方法的理论仿真和结果分析。代码以附在之后。(Code to achieve the optimum weights recursive second order AR model, the use of LMS and RLS are two methods were compared for the two properties, were observed and 100 times the average per-performance and simulated sync Effect of a growth factor RLS algorithm impact on LMS algorithm and different lamda value. Document contains the results of theoretical simulation and detailed description of the model and two methods of analysis. Code annexed.)
