RMLN Wireless Channel Model And Applications In The Iot Of Human Body

Research on wireless channel model is critical to analyze the characteristics of wireless propagationinformation.The statistical characteristics(one order and two order)and parameter estimation are an important index to describe the propagation performance of the channel.Based ondomestic and foreign experts put forward the channel model to study the channel of RMLNmodels(RM?LN?RMLN)characteristics and parameters.And the RMLN channel model is used in the body of things.According to use matlab simulationcomparing the statistical properties of the measured data and simulation data,it is proved that the model can reliablydescribe human networking.The main work and results are as follows:(1)The cumulative distribution function of statistics(CDF)calculation formula is the first time that derived in the RM?LN?RMLN model,and first order statistical properties and get the simplest expressions.And the simulation of RMLN channel model by using matlab tools,the simulation and theoretical derivation of the PDF and CDF results show that the derived reliability.(2)Based on the statistical frequency pass rate(LCR),average fade duration(AFD)formula to derivethe RM?LN?RMLN model and two order statistics the first time and get the simplest expressions.The simulation ofRMLN channel model by using matlab tools to compare the simulation and theory derivation of the LCR,the curve results show thatthe theory of AFD is reliability.(3)The parameters of the RMLN channel model are derived for the first time by using the method of logarithmic moment estimation in the parameter estimation method.(4)The frequency of test data transmission of human 4.4GHz networks using a vector network analyzer.Characteristics of RMLN channel model to describe the network spread of the human body is discussed.By using matlab tools,the statistical characteristics are given theoretical and experimental comparison curve,the results show that the RLMN channel model can be used in the body of things,and that the correctness of the theory of the fourth chapter.
