Abstract :
A multiple signal classification (MUSIC)-based approach, time-space-time MUSIC (TST-MUSIC), is proposed to jointly estimate the directions of arrival (DOAs) and the propagation delays of a wireless channel. The MUSIC for the DOA and the propagation delay estimation are referred to as the S-MUSIC and the T-MUSIC, respectively. Using the space-time characteristics of the multiray channel, the proposed algorithm in a tree structure combines the temporal filtering techniques and the spatial beamforming techniques with one S-MUSIC and two T-MUSICs. The incoming rays are thus grouped, isolated, and estimated.
