1. An operation method of a first communication node in a communication system, the operation method comprising:
determining whether each of one or more interference signals satisfies a line-of-sight (LOS) condition or a non-line-of-sight (NLOS) condition, the one or more interference signals being received through a first antenna composed of a plurality of antenna elements;
estimating incident direction(s) of the one or more interference signals;
performing spatial filtering based on the incident direction(s) of the one or more interference signals, with respect to each of a plurality of array antenna combinations each of which is determined at least in part based on some of the plurality of antenna elements; and
receiving wireless signals based on a result of the spatial filtering,
wherein incident direction(s) of NLOS interference signal(s) corresponding to the NLOS condition among the one or more interference signals are estimated based on p largest eigenvalue vectors and q smallest eigenvalue vectors among a plurality of eigenvalue vectors obtained based on a first direction finding (DF) algorithm, p and q being natural numbers.
