TDOA assisted RSSD based localization using UWB and directional antennas
This paper studies the use of directional antennas for received signal
strength difference (RSSD) based localization using ultra-wideband and
demonstrates the achievable accuracy with this localization method applied to
UWB. As introduced in our previous work the RSSD localization is assisted with
one Time Difference of Arrival (TDOA) estimation. The use of directional
receiving antennas and an omni-directional transmitting antenna is assumed.
Localization is performed in 2D. Two localization approaches are considered:
RSSD using statistical channel model and fingerprinting approach. In the case
of statistical channel model simulations are performed using Matlab. In the
case of fingerprinting approach localization is done based on real
indoor-measurements
