Distributed expectation-maximization algorithm for DOA estimation in wireless sensor networks

In this paper, we study the problem of using distributed expectation-maximization (EM) for direction-of-arrival (DOA) estimation over wireless sensor networks, where each node is equipped with multiple sensor elements. It is a diffusion adaptation strategy based EM algorithm, which is applicable for...
