The performance of adaptive algorithms, including direct data domain least square, can be significantly degraded in the presence\nof mutual coupling among array elements. In this paper, a new adaptive algorithm was proposed for the fast recovery of the signal\nwith one snapshot of receiving signals in the presence of mutual coupling, based on the two-dimensional direct data domain least\nsquares (2-D D3LS) for uniform rectangular array (URA). In this method, inverse mutual coupling matrix was not computed.\nThus, the computation was reduced and the signal recovery was very fast. Taking mutual coupling into account, a method was\nderived for estimation of the coupling coefficient which can accurately estimate the coupling coefficient without any auxiliary\nsensors. Numerical simulations show that recovery of the desired signal is accurate in the presence of mutual coupling.
