FER regression analysis of DS-UWB-based WPAN

Ultra-Wideband (UWB) technology is at present defined as any wireless transmission scheme that occupies a fractional bandwidth ges20%, or more than 500 MHz of absolute bandwidth. In this paper we have considered an UWB system, based on Direct Sequence - UWB (DS-UWB) proposal standard, in an indoor multipath environment modeled in accordance with IEEE 802.15 channel modeling subcommittee. Performance are evaluated in terms of frame error rate (FER) vs. transmitter-receiver distance and frame size and finally a polynomial regression analysis is carried out on simulation results in order to obtain a closed formula to describe, for different scenarios, the FER as a function of data rates, frame size and distance between transmitter and receiver.
