| Abstract | ||||
| This paper is concerned with introducing a system for reducing the effect of coherent interference sources. This system consists of two units connected with an adaptive antenna array. The first is concerned with the direction of arrival (DOA) estimation of incident signals. The second is used for generating adaptive nulls in the direction of undesired interference. Modified Multiple Signal Classification (Modified MUSIC) algorithm is used for estimating the DOA. Also, an adaptive method for generating nulls in the direction of undesired interferences is introduced and it is denoted by Complementary Transformed Minimum Variance (CTMV) beam former. Computer simulations indicate that the proposed system is robust in presence of coherent and non-coherent interferences. | ||||
