RSSI强度值采集例子，每隔一段距离采集一段RSSI值，从matlab中绘制折线图，并由最小二乘法分析你合成曲线(RSSI strength values ​ ​ collected examples, at some distance acquisition period of the RSSI value, the last drawing, analyze your synthetic curve by the least squares method)

这个是利用MATLAB实现的KNN算法的实现(This is achieved using MATLAB algorithm to achieve KNN)

s in academia, and in the military. In fact, in some sense, the 3D graphics we enjoy on our PCs today is a sort of Peace Dividend, since many professionals now working in the 3D chip, film and game development industries cut their teeth designing military simu

Signal processing front end for extracting the feature set is an important stage in any speech recognition system. The optimum feature set is still not yet decided. There are many types of features, which are derived differently and have good impact on the recognition rate. This paper presents one more successful technique to extract the feature set a speech signal, which can be used in speech recognition systems. Our technique based on the human auditory system characteristics and relies on the gammachirp filterbank to emulate asymmetric frequency response and level dependent frequency response.
