We report on the proximity detection of a moving object tagged with a passive Ultra High Frequency (UHF) Radio Frequency Identification (RFID) tag compared to a stationary tag and the recognition of predefined movement trajectories of tagged objects. Both methods are based on sequentially received t…
Gaussian processes (GP’s) have been used to predict acoustic fields by interpolating under-sampled field observations. Using GP interpolation to predict fields is advantageous because of its ability to denoise measurements and for its prediction of likely field outcomes given a certain field coheren…
Recent investigations indicate that Sparse Bayesian Learning (SBL) is lacking in robustness. We derive a robust and sparse Direction of Arrival (DOA) estimation framework based on the assumption that the array data has a centered (zero-mean) complex elliptically symmetric (ES) distribution with fini…
The paper considers direction of arrival (DOA) estimation from long-term observations in a noisy environment. In such an environment the noise source might evolve, causing the stationary models to fail. Therefore a heteroscedastic Gaussian noise model is introduced where the variance can vary across…
