MUSIC angle of arrival estimation algorithms

描述一种信道，通过卡尔曼滤波器对信道信号进行估计(A channel described by the Kalman filter to estimate the channel signal)

DC-DC和DC-AC仿真，matlab实现(DC-DC and DC-AC simulation, matlab implementation)

本人编写的QC-LDPC码的完整实现，采用阵列校验矩阵，极其简单，适合入门(A easy-to-learn source code of QC-LDPC encoder)

说明：  本人制作的关于改进人工势场的发表资料。里面包括了关于传统人工势场的理解，和改进人工势场的仿真(I made about the release of improved artificial potential field data. Which includes the traditional artificial potential field on the understanding, and improve the simulation of artificial potential field)

该算法在原有的算法基础上提出的TDOA泰勒算法，可以用在传感器定位和蜂窝网定位。且该算法的定位精度比较高。(The algorithm is based on the original algorithm proposed TDOA Taylor algorithm can be used in sensor positioning and cellular location. And the algorithm is relatively high positioning accuracy.)

实现MIT数据库ECG信号的读取，并进行QRS波形的检测(ECG signal MIT database achieved the reading, and for detection of QRS wave)

POM 模式在linux 系统中作netcdf输出后可以用此MATLAB插件作数据处理(POM model for the system in linux can use this after the netcdf output for data processing MATLAB plug-in)

该文档给出了通信原理中的数字调制和解调的matlab程序代码，如BPSK,QPSK,QAM等等调制方式。(the document is a communication principle of digital modulation and demodulation of the Matlab code. such as BPSK, QPSK, QAM modulation mode, and so on.)

说明：  滚动轴承故障诊断是机械故障检测中一个重要方面。使用小波包分析和包络分析相结合的方法提取轴承微弱振动信号, 克服了传统包络分析方法易丢失信号有效成分的缺点。包络信号的细化谱较好体现了轴承故障信息。(Bearing Fault Diagnosis of mechanical fault detection in an important aspect. The use of wavelet packet analysis and envelope analysis method of combining extracts bearing vibration signal weak to overcome the traditional envelope analysis method easy to lose the signal disadvantage of the active ingredient. Refinement of the envelope signal spectrum better reflects the bearing fault information.)
