Abstract

Conventional generalized sidelobe canceller (GSC) is sensitive to coherent multipath disturbance in wireless communication environments. Such disturbance, including coherent interference and local scattering, causes signal cancellation in the GSC. In this paper, we propose a new decision feedback (DF) technique to overcome this problem. The proposed algorithm introduces a feedback filter with one tap weight in the GSC structure. We analyze the robustness of this algorithm and the result shows that the problem of signal cancellation can be avoided. Simulations demonstrate that the DF-GSC has greatly improved robustness as compared to the conventional GSC.
