Direction-of-Arrival Estimation Based on Sparse Recovery with Second-order Statistics
Traditional direction-of-arrival (DOA) estimation techniques perform Nyquist-rate sampling of the received signals and as a result they require high storage. To reduce sampling ratio, we introduce level-crossing (LC) sampling which captures samples whenever the signal crosses predetermined reference levels, and the LC-based analogto-digital converter (LC ADC) has been shown to efficiently sampl...
متن کاملBroadband Direction-Of-Arrival Estimation Based on Second Order Statistics
N wideband sources recorded using N closely spaced receivers can feasibly be separated based only on second order statistics when using a physical model of the mixing process. In this case we show that the parameter estimation problem can be essentially reduced to considering directions of arrival and attenuations of each signal. The paper presents two demixing methods operating in the time and...

متن کاملDirection of Arrival Estimation using a Sparse Linear Antenna Array
1057 Abstract—This paper presents the use of Inverse Free Krylov Subspace Algorithm (IFKSA) with Estimation of Signal Parameter via Rotational Invariance Technique (ESPRIT), for Direction-of-Arrival (DOA) estimation using a Sparse Linear Array (SLA) of antenna elements. The use of SLA reduces the hardware requirements and the production cost. The SLA generates the sparse data, the pure signal s...
