Abstract :
A multi-dimensional parameters joint estimator by Gibbs-MUSIC method (GSM) is proposed to jointly estimate the azimuth and elevation of multiple sources. In this method, the power of MUSIC spectrum function is regarded as target distribution up to a constant of proportionality, and Gibbs sampling is done on this distribution. Simulation results show that this new method preserves the performance of high-resolution in conventional MUSIC and reduces computation and storage costs at the same time when signal sources are quite limited.
