Bayesian Compressive Sensing for DOA Estimation using the Difference Coarray
, 2020 -In this paper, we utilize Bayesian Compressive Sensing (BCS) for direction-of-arrival (DOA) estimation based on the coarray. This enables estimation of more sources than the number of physical antennas. We adopt the covariance vectorization technique to

Comparison of Sparse Arrays From Viewpoint of Coarray Stability and Robustness
, 2018 Sparse arrays, such as minimum redundancy arrays (MRA), nested arrays, and coprime arrays, can resolve O(N^2), uncorrelated sources with N physical sensors, since they possess an O(N2) -long uniform segment in the difference coarray, which is defined as ...

Robustness of Coarrays of Sparse Arrays to Sensor Failures
, 2018 Sparse arrays can identify O(N^2) uncorrelated sources using N physical sensors. This property is because the difference coarray, defined as the differences between sensor locations, has uniform linear array (ULA) segments of length O(N^2) .

Joint Phased-MIMO and Nested-Array Beamforming for Increased Degrees-of-Freedom
International Journal of Antennas and Propagation, 2015 Phased-multiple-input multiple-output (phased-MIMO) enjoys the advantages of MIMO virtual array and phased-array directional gain, but it gets the directional gain at a cost of reduced degrees-of-freedom (DOFs).
