收发同时技术中的数字相消技术研究
发布时间:2019-06-03 13:33
【摘要】:在电子系统中,有时需要在同一平台上实现同时进行信号的接收和发射。收发同时条件下对强耦合干扰信号相消需要更短的数据和更高的相消效果,而一般因果对消器相消性能较差。文章提出了采用非因果滤波器进行数字对消的技术。首先建立了非因果滤波器数字对消模型,然后对数字对消进行了仿真分析。仿真说明了数字相消的优异特性,并表明了在相同滤波器阶数的情况下,非因果滤波器数字对消法有更好的对消效果。
[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.
