Analysis of optimization for properties of UWB indoor multipath channel
Abstract
Methods of optimization were proposed for analyzing the properties of UWB indoor multipath channels,and a mathematical model for UWB channel modeling was discussed.Assumptions of stochastic bridge process and probabilistic choice were adopted.A UWB channel impulse response based on bounded Brownian bridge model （BBBM） was constructed.The judgments of effective random paths,and modeling algorithms based on the methods of optimization were presented.The results of simulation for UWB channels demonstrated that the BBBM could obtain the similar properties to the ones of experiments and UTD methods,some characteristic parameters corresponded well with the experimental values.
