Abstract

Based on an equivalent transformed network, the performance of an adaptive array with mutual coupling compensation is analyzed in detail. It is indicated that the adaptive array with mutual coupling compensation can suppress interference thoroughly. However, the output power of noise changes with the direction of the desired signal, which causes the degradation of the output signal-to-interference-plus-noise ratio (SINR). Therefore, it is mainly the thermal noise after mutual coupling compensation that results in output SINR degradation. Finally simulation results verify our conclusions
