本文考虑了一种具有同时分布式发射波束成形和零值成形的无线通信系统。除了控制发射机相位以提供方向性的常用方法之外，分布式阵列中的一个或多个节点还调整其位置以提高波束质量而不损失零点质量。本文提出了一种具有简单反馈的自适应算法，以促进节点定位，从而对一个所需接收器实现最佳波束成形，同时将零点引导到一个或多个受保护的接收器。通过仿真证明了自适应算法的有效性。
This paper considers a wireless communication system with simultaneous distributed transmit beamforming and nullforming. In addition to the usual method of controlling the phases of the transmistters to provide directivity, one or more nodes in the distributed array also adapt their position(s) to improve the quality of the beam without loss of null quality. This paper presents an adaptive algorithm with simple feedback to facilitate node positioning such that optimal beamforming is achieved to one desired receiver while simultaneously steering nulls to one or more protected receivers. The efficacy of the adaptive algorithm is demonstrated via simulation.
