Extension of Co-Prime Arrays Based on the Fourth-Order Difference Co-Array Concept [PDF]
IEEE Signal Processing Letters, 2016 An effective sparse array extension method for maximizing the number of consecutive lags in the fourth-order difference co-array is proposed, leading to a novel enhanced sparse array structure based on co-prime arrays (CPAs) with significantly increased number of degrees of freedom (DOFs). One method to exploit the increased DOFs based on nonstationary

Modal Analysis Using Co-Prime Arrays [PDF]
IEEE Transactions on Signal Processing, 2016 We address the problem of estimating mode parameters from noisy observations of a linear combination of the corresponding modes. This problem arises in line spectrum estimation, vibration analysis, speech processing, system identification, and direction of arrival estimation. Our results differ from standard results of modal analysis to the extent that
