- W2945786626 abstract "SummaryAn analysis is presented on the influence of multipath fading on the ranging methodproposed by Haartsen [1]. The considered method uses the Bluetooth radio system,which has as advantage that the ranging method may in the future be added tothe Bluetooth standard. The current standards for indoor ranging leave room forimprovement. As such it is interesting to show how this method will be influenced bythe indoor environments.Typically indoor environments have many reflective paths a signal can travel bybetween transmitter and receiver. Therefore, the goal of this thesis is to determinethe impact of multipath propagation on the ranging method’s performance.The impact of a multipath channel is shown analytically and verified by simula-tion. The performance is measured in the mean square error of the ranging estimate,including both noise and channel effects.Using the simulator and the analysis, it is shown that they are in accordance witheach other within the expected parameter ranges. The most noteworthy boundariesare the required signal-to-noise level, sampling frequency of the simulator and thedelay spread.Finally it is concluded that the ranging method requires a high K-factor and largesignal-energy-to-noise ratio. The mean square error of the estimate relates roughlyquadratically to the delay spread. This leads to undesirably high mean square errorsfor moderate delay spreads." @default.
