Sparse Sensing with Semi-Coprime Arrays
, 2018 A semi-coprime array (SCA) interleaves two undersampled uniform linear arrays (ULAs) and a $Q$ element standard ULA. The undersampling factors of the first two arrays are $QM$ and $QN$ respectively where $M$ and $N$ are coprime. The resulting non-uniform linear array is highly sparse.

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

Tensor MUSIC in Multidimensional Sparse Arrays
, 2015 Tensor-based MUSIC algorithms have been successfully applied to parameter estimation in array processing. In this paper, we apply these for sparse arrays, such as nested arrays and coprime arrays, which are known to boost the degrees of freedom to O(N2 ...
