Abstract

In this paper the matrix pencil technique is applied to reduce interference caused by multipath signals in antenna patterns. The finite difference time domain method is used to get the time-domain signals as in free space and under interference. Then, the gating technique and the matrix pencil method are used to clean that interference. The results show the efficacy of the matrix pencil method when compared with the gating technique.
