Efficient and Robust Adaptive Beamforming Based on Coprime Array Interpolation

Remote Sensing
Unlike uniform linear arrays (ULAs), coprime arrays require fewer physical sensors yet provide higher degrees of freedom (DOF) and larger array apertures.

Novel coprime MIMO configurations for DOA estimation with increased degrees of freedom

Franklin Open
In this work, we propose some coprime multiple input multiple output (MIMO) configurations for direction-of-arrival (DOA) estimation, which achieve more degrees of freedom (DOF) than all the existing coprime MIMO configurations. We know that in a coprime
