Adaptive Measurement Matrix Design in Direction of Arrival Estimation
IEEE Transactions on Signal Processing, 2022 Advances in compressed sensing (CS) theory have brought new perspectives to encoding and decoding of signals with sparse representations. The encoding strategies are determined by measurement matrices whose design is a critical aspect of the CS applications.

Direction of arrival estimation using nonsingular spherical ESPRIT [PDF]
The Journal of the Acoustical Society of America, 2018 The eigenbeam-ESPRIT (EB-ESPRIT) is a parametric method that estimates the direction of arrival of source signals using a recurrence relation of spherical harmonics. In EB-ESPRIT, the sound-source elevation angle is estimated from an arctangent function, which diverges near the equator in the spherical coordinate system and inevitably induces an ill ...
