In this article, an adaptive antenna system (AAS) based on a time-modulated antenna array (TMAA) and population-based metaheuristic algorithm is presented. The algorithm is driven by the signal-to-noise ratio measurements and provides real-time adaptation of the antenna pattern. This article also addresses the issue of multiband reception with a TMAA, demonstrating that the sidebands generated from frequency-diverse signals can overlap and interfere. The effectiveness of the AAS as part of a wireless communication system is presented in three different experimental scenarios that consider gradually or rapidly changing conditions as well as the interference caused by the reception of two signals with different carrier frequencies.

用于宽带无线系统实时自适应的时间调制天线阵列第二部分：自适应研究


在本文中，提出了一种基于时间调制天线阵列（TMAA）和基于群体的元启发式算法的自适应天线系统（AAS）。该算法由信噪比测量驱动，并提供天线方向图的实时自适应。本文还讨论了使用 TMAA 进行多频段接收的问题，证明了频率分集信号生成的边带可能会重叠和干扰。 AAS 作为无线通信系统一部分的有效性在三个不同的实验场景中展示，这些场景考虑了逐渐或快速变化的条件以及由接收具有不同载波频率的两个信号引起的干扰。
