用matlab写的以太网报头提取工具。它可以截获网络数据包并记录下它的时间戳、数据包长度和数据域等。(Written by matlab Ethernet header extraction tool. It can be intercepted network packets and record its timestamp, packet length and data domains such as.)

先用butter filter去除噪音，再找到信号峰，对峰描叙的条件可以自行调整(butter filtering, and peak finding)

第一个是标准差，用于算数学模型均值，评价模型的平均量 第二个熵，用于评价信息量的大小，熵越大信息量越大。 第三个用于pcnn模型,评价是否接近理论模型,残差越小，就越接近理论模型(The first is the standard deviation, the mathematical model is used to calculate the mean, the average amount of uation model. The second entropy, to uate the size of the amount of information, the greater the entropy the greater the amount of information. The third for PCNN model, uation is close to the theoretical model, residual error is smaller, the more close to the theoretical model)

RSSI算法是指根据无线传感器接受到（目标物体）的信号指示强度，计算该信号在传播中的损耗，根据理论或者经验的信号传播模型将信号强度转换成距离。但是这种算法很容易受到天气，障碍物或人员流动的影响，导致测距不精确，从而定位精度不高。但是由于RSSI算法简单，成本低廉，很多无线通信模块提供RSSI值，所以RSSI算法依然应用在众多领域中。(RSSI algorithm is based on wireless sensor to receive the signal intensity (objects), calculate the signal in the transmission loss, according to the experience of the theory or the signal propagation model will be converted into a distance of signal strength.But this algorithm is very vulnerable to weather, obstacles or the influence of the flow of people, lead to range is not accurate, thus positioning accuracy is not high.But because the RSSI algorithm is simple, low cost, a lot of wireless communication module provides RSSI values, so the RSSI algorithm is used in many fields.)
