Abstract

The estimation of the direction of arrival (DOA) and the estimation of the number of signal sources are very important techniques in modern communications. The effect of mutual coupling can degrade the performance of the estimation algorithms. Mutual coupling compensation is used to mitigate this effect. However, errors remain when the compensation is carried out with such methods as minimum description length (MDL) to estimate the number of signal sources. This work presents a new method based on threshold decision to estimate the number of signal sources in presence of mutual coupling. The results of computer simulations demonstrate that the proposed method outperforms the MDL method.
