摘要:

在过去的几十年里,从单个天线阵列观测估计源的数量及其到达角的问题一直是信号处理界的一个活跃的研究领域。当源的数量很大时,最大似然估计器由于其非常高的复杂性而难以处理,因此已经开发了具有一些性能损失的替代信号处理方法。在本文中,我们将深度神经网络(DNN)方法应用于该问题,并分析其相对于信号处理算法的优势。我们表明,一个适当的设计网络可以达到最大似然性能与可行的复杂性和优于其他可行的信号处理估计方法在各种信号噪声比和阵列响应不准确。

英文摘要:

The problem of estimating the number of sources and their angles of arrival from a single antenna array observation has been an active area of research in the signal processing community for the last few decades. When the number of sources is large, the maximum likelihood estimator is intractable due to its very high complexity, and therefore alternative signal processing methods have been developed with some performance loss. In this paper, we apply a deep neural network (DNN) approach to the problem and analyze its advantages with respect to signal processing algorithms. We show that an appropriate designed network can attain the maximum likelihood performance with feasible complexity and outperform other feasible signal processing estimation methods over various signal to noise ratios and array response inaccuracies.
