Abstract

In this paper, we evaluate the performance of the JADE-MUSIC (joint angle and delay estimation) algorithm in the presence of point sources. The observed snapshots are used to estimate the space-time channel matrix. The estimated channel matrix is then used to jointly estimate the direction of arrival and the time of arrival. The performance of the JADE-MUSIC algorithm is then evaluated in terms of bias and mean square error of the DOA and TOA estimates. The obtained results are also compared to the Cramer-Rao bound.
