ABSTRACT

This Paper evaluates, the operations of Ultra-Wideband (UWB) system based Multiband-Orthogonal Frequency Division Multiplexing (MB-OFDM) channel models at Indoor conditions. In recent days the UWB plays vital role for short-range of communication with remarkably high speed. The main focus on channel models created from Modified S-V model. The MB-OFDM is utilized in wireless communication in recent years owing to its high transmitting speed as well as excellent immunity in multiple paths. UWB OFDM based system is designed representing physical layer in IEEE 802.15.4a standard. The UWB provided channel models in support of both LOS and NLOS of indoor residential, office, industrial, outdoor, and one open outdoor environment (NLOS). The four indoor channel models are observed with simulation results that elaborates the UWB indoor Channel Models performance of IEEE802.15.4a.
