Unfolded Coprime Transformed Nested Arrays for Increased DOF and Negligible Mutual Coupling

In this work, we propose the unfolded versions of the coprime transformed nested array (CTNA), which exploits the sum difference coarray (SDCA). We know that the CTNA has attractive properties in achieving more degrees of freedom (DOF) in direction-of-arrival estimation. However, the mutual coupling...
