GOSSIP ALGORITHM-BASED SINGLE-TARGET DOA ESTIMATING SYSTEM AND ESTIMATING METHOD IN DISTRIBUTED NETWORK

摘要

The present invention relates to a gossip algorithm-based single-target DOA estimating system and estimating method in a distributed network. The inversion operation of said system and method utilizes a noise diagonal matrix to substitute for an autocorrelation matrix of the received signals of all nodes, thereby avoiding the method in traditional algorithms of the received signals of all nodes requiring centralised processing, and thus providing a good estimate of single target DOA values.
