Abstract

In this paper, the performance of mutual coupling compensation in adaptive arrays is studied. It is indicated that the adaptive array after mutual coupling compensation can suppress interference thoroughly. However, the output power of noise changes with the direction of desired signal, which causes the degradation of the output signal-to-interference-plus-noise ratio (SINR). Therefore, the thermal noise is mainly responsible for the output SINR degradation after mutual coupling compensation. This conclusion derived from the paper is expected to be valuable for the engineering application of an adaptive array. The simulation results demonstrate further the conclusions
