Abstract EN
An automatic pairing joint direction-of-arrival (DOA) and frequency estimation is presented to overcome the unsatisfactory performances of estimation of signal parameter via rotational invariance techniques- (ESPRIT-) like algorithm of Wang (2010), which requires an additional pairing.
By using multiple-delay output of a uniform linear antenna arrays (ULA), the proposed algorithm can estimate joint angles and frequencies with an improved ESPRIT.
Compared with Wang’s ESPRIT algorithm, the angle estimation performance of the proposed algorithm is greatly improved.
The frequency estimation performance of the proposed algorithm is same with that of Wang’s ESPRIT algorithm.
Furthermore, the proposed algorithm can obtain automatic pairing DOA and frequency parameters, and it has a comparative computational complexity in contrast to Wang’s ESPRIT algorithm.
By the way, this proposed algorithm can also work well for nonuniform linear arrays.
The useful behavior of this proposed algorithm is verified by simulations.
