The Simulation and Analysis of UWB Modified S-V Channel Model

Due to the advantages of high transmission speed, great system storage, excellent multipath immunity capacity, limited power wastage and low cost, ultra-wideband technology is considered a key technology to next generation wireless communication. Channel models are fundamental to the study and design of communication systems. This paper gives a survey on indoor wireless channels for UWB radio, and introduces UWB channel models, including the Poisson model, the Delta-K model, the S-V model, and the IEEE802.15.3a model. Modeling method and characterization of these models are covered. Finally, in allusion to indoor channel multipath arriving in clusters, the modified S-V model is described and used to simulate the UWB channel model, simulation results of the model are presented. It is shown that the channel model approaches well to the measured result of UWB channel.
