TLDR
In this paper, the mutual coupling compensation in uniform linear and circular receiving antenna arrays of thin wire dipoles is presented, and it is observed that the mutual impedance is independent of the incident angle and depends solely on the geometry of the array.Abstract:
Mutual coupling compensation in uniform linear and circular receiving antenna arrays of thin wire dipoles is presented. It was observed that the mutual impedance is independent of the incident angle and depends solely on the geometry of the array. By using only one measurement, decoupling matrix is computed and direction of arrival is estimated.read more

Impact of Mutual Coupling on Power-Domain Non-Orthogonal Multiple Access (NOMA)
TL;DR: Simulation results show that mutual coupling degrades the sum-rate performance of the NOMA system in all three array structures, especially in the UCA structure due to the smaller spacing of the array element in a circular shape, but compensating the mutual coupling effect by the MOM technique in the case of unknown MC or matrix inversion significantly improves the system sum- rate in all scenarios.

Mutual coupling effect in multiantenna wireless communication systems
TL;DR: It is shown that mutual coupling can be expressed in terms of individual couplings due to antenna array geometry, near-field scatterers (NFS), and DOA, and for MIMO and spatial diversity, DOA dependency drops since the feeding network does not have to be changed for a given DOA.
