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

摘要

The present invention relates to a gossip algorithm based multiple target DOA estimating method in a distributed network. The present invention, on the basis of the required number of iteration cycles for a DOA estimated value calculated on the basis of a DOA estimated value calculation formula, uses a gossip algorithm to continuously update the signal components for DOA estimation until the ideal state for full information sharing is reached, and, after executing all the iteration cycles, can obtain a good DOA estimate. The present invention does not require a matrix inversion method, and can implement information sharing and DOA value estimation in a distributed network.
