An Effective Technique for Enhancing Anti-Interference Performance of Adaptive Virtual Antenna ArrayAbstract
In this paper, we proposed an effective technique to enhance the anti-interference performance of the adaptive antenna arrays. The null depth in the direction of interferers determines the anti-interference performance of an adaptive antenna array. However, the null depth generated by the conventional virtual array transformation (VAT) algorithm is usually not sufficient. By introducing the interference direction information into the transformation matrix, we can effectively improve the level of null depth; in turn, the anti-interference performance of the adaptive antenna arrays is significantly enhanced. The numerical experiments are employed to validate the proposed approach.
