In this paper, space-delay adaptive processing (SDAP) is proposed for motion mapping using MIMO RF signals. Typically, indoor RF localization methods require ultra-wideband signals to achieve the time-delay resolution required for separation of returns in complex multipath environments. Due to spectrum use restrictions, however, there is a need for methods which can operate using the lower bandwidths...
To realize precise localization for UWB backscattering RFID system, the arrival time of the direct path in the received signal (referred as time of arrival (TOA)) needs to be accurately estimated. The background clutter is one of the major factors that deteriorates the TOA estimation accuracy in backscattering RFID system. To suppress the background clutter while maintain low‐complexity system design,...
