Abstract

In wireless communications, there are two problems that the systems suffer from, one is the inter-symbol interference (ISI), the other is the cochannel interference (CCI). Space-time adaptive processing (STAP) is considered to provide superior performance in suppressing both the ISI and the CCI. To reduce the complexity and the cost, using switched parasitic elements or the parasitic elements with variable reactances to change the mutual coupling and so as to provide spatial diversity attracts much attention. The electronically steerable passive array radiator (ESPAR) antenna is one of the parasitic elements based single port antennas with several variable reactances. We propose a single port ESPAR antenna-based space-time adaptive filtering. Unlike the nulls formed by the conventional adaptive antenna, here we develop the potential of jointly using the variable pattern and the temporal equalizer to realize space-time adaptive filtering.

基于空时自适应滤波的单端口电子操纵无源阵列辐射天线

在无线通信中，系统面临着两个问题，一个是码间干扰(ISI)，另一个是共信道干扰(CCI)。时空自适应处理(STAP)被认为在抑制ISI和CCI方面都具有优异的性能。为了降低系统的复杂性和成本，利用开关寄生元件或可变电抗寄生元件来改变系统的相互耦合，从而提供空间多样性受到了广泛的关注。电子操纵无源阵列辐射器(ESPAR)天线是一种基于寄生元件的单端口可变电抗天线。提出了一种基于单端口ESPAR天线的时空自适应滤波方法。与传统自适应天线形成的空区不同，本文开发了利用变方向图和时间均衡器共同实现空时自适应滤波的潜力。
