An Empirical Interference Modeling for Link Reliability Assessment in Wireless Networks(Abstract—In recent years, it has been widely believed in the community that the link reliability is strongly related to received signal strength indicator (RSSI) [or signal-to-interference-plus-noise ratio (SINR)] and external interference makes it unpredictable,which is different from the previous nderstanding that there is no tight relationship between the link reliability and RSSI (or SINR), but multipath fading causes the unpredictability. However,both cannot fully explain why the unpredictability appears in the link state. In this aper, we unravel the following questions: 1) What causes frame losses that are directly related to intermediate link states? 2) Is RSSI or SINR a right criterion to representthe link reliability? 3) Is there a better easure to assess the link reliability? We fi rst confi gured a testbed for performing a real measurement study to identify the causes of frame losses, and observed that link reliability depends on an intraframe SINR distribut)

Robotics TOOLBOX The Toolbox provides many functions that are useful in robotics including such things as kinematics, dynamics, and trajectory generation. The Toolbox is useful for simulation as well as analyzing results from experiments with real robots. Have fun with the toolbox. It is self-explanatory and very (robotics) user friendly...see the robot.pdf

本程序描述了ofdm的程序，并对程序进行了仿真，并对仿真结果进行了分析(This procedure describes the procedures for ofdm, and process simulation, and simulation results are analyzed)

ESPRIT算法是一种用于信号到来角(DOA)估计的直接求解方法,本程序中含有3种不同的算法均为自编(ESPRIT algorithm is used to signal the arrival angle (DOA) estimation of the direct methods, its performance at low signal to noise ratio (SNR) and signal correlation will seriously undermine)

自己编写的一个单载波时域均衡的程序，采用的是线性MMSE均衡算法(When I have written a single carrier domain equalization program, using the linear MMSE equalization algorithm)

fuzzy_cluster模糊聚类分析，本函数使用的是直接聚类法，直接输出聚类信息，无返回值 输入参数data是需要分类的数据，将会对data的列分类，请输入数据前把需要分类的向量按列保存到矩阵data 输入参数numda是分类的分类点，如果不知道可以先省略，系统默认1-0依次减小用以方便判断分割点，然后用户再细分( Fuzzy_cluster fuzzy clustering analysis, the function uses the clustering method is direct, direct output clustering information, no return value input parameter data is needed to classify data, classification of data will be listed, enter the data before the need saved by the column vector classification matrix data to the input parameters numda profile classification point is, if you do not know can be omitted, in order to reduce the system default 1-0 split point for easy judgment, then the user is subdivided)
