摘要

到达方向估计在无线通信中是不可缺少的，它在到达方向定位和下行波束形成中起着至关重要的作用。本文介绍了标准正交原子范数最小化(OANM)的概念和实际实现，OANM是一种新颖的压缩感知方法，可用于doa估计，并且仅使用接收信号的单快照，更无天线间间距分离。结果表明，该方法能够较好地估计不同用户传输的信号的doa，且复杂度低，效率高。

OANM: An Atomic Separation-free Solution for DoA-estimation in Wireless Communication

Direction-of-Arrival (DoA)-estimation is indispensable in the industry of wireless communication, for example, it is pivotal in DoA-localization and downlink beamforming. In this paper, we introduce the concept and practical implementation of Orthonormal Atomic Norm Minimization (OANM), a kind of innovative way of compressive sensing, which can be used for DoA-estimation and is more inter-antenna spacing separation-free with the usage of only single-snapshot of received signal. The result shows that OANM can successfully estimate the DoAs of signals transmitted by all different users with low complexity but high efficiency.
