The degree of freedom (DOF) is a key indicator of the spatial multiplexing layers of a wireless channel. Recent studies suggest that the DOF of a multiple-input and multiple-output could be less than the antenna number when strong mutual coupling is considered. To this end, We utilized a mutual-coup...
