【摘要】:在電子系統(tǒng)中,有時需要在同一平臺上實現(xiàn)同時進行信號的接收和發(fā)射。收發(fā)同時條件下對強耦合干擾信號相消需要更短的數(shù)據(jù)和更高的相消效果,而一般因果對消器相消性能較差。文章提出了采用非因果濾波器進行數(shù)字對消的技術。首先建立了非因果濾波器數(shù)字對消模型,然后對數(shù)字對消進行了仿真分析。仿真說明了數(shù)字相消的優(yōu)異特性,并表明了在相同濾波器階數(shù)的情況下,非因果濾波器數(shù)字對消法有更好的對消效果。
[Abstract]:In electronic systems, it is sometimes necessary to receive and transmit signals at the same time on the same platform. The cancellation effect of strong coupling interference signal needs shorter data and higher cancellation effect under the condition of receiving and receiving at the same time, but the cancellation performance of general causality canceller is poor. In this paper, a technique of digital cancellation using non-causality filter is proposed. Firstly, the digital cancellation model of non-causality filter is established, and then the simulation analysis of digital cancellation is carried out. The simulation shows the excellent characteristics of digital cancellation, and shows that the non-causality filter digital cancellation method has a better cancellation effect under the same filter order.
