サンプル点間応答を考慮した回り込み波キャンセラのH∞ 最適設計

Abstract

In this article, we propose H∞ optimal design of digital filters that cancel the continuous-time effect of coupling waves in a single frequency full-duplex relay station from the transmitter to the receiving antenna. In this study, we model a relay station as a continuoustime system while conventional researches treat it as a discrete-time system. For this model, we design digital filters via the theory of sampled-data H∞ control for cancellation of coupling waves. Numerical experiments show the effectiveness of the proposed method.
