Statistically Efficient Methods for Pitch and DOA Estimation [PDF]

, 2013
Traditionally, direction-of-arrival (DOA) and pitch estimation of multichannel, periodic sources have been considered as two separate problems. Separate estimation may render the task of resolving sources with similar DOA or pitch impossible, and it may ...

Broadband DOA Estimation by Exploiting DFT Extrapolation

, 2023
This study proposes broadband direction (DOA) estimation through discrete Fourier transform (DFT) extrapolation. We used DFT extrapolation in the lower band and extended the sampled data to reduce the beam width in the spectral domain and improved the ...

About the Use of Adaptive Antennas in 60 GHz UWB-OFDM Personal Area Network Transceivers

, 2008
The recent opening of unlicensed spectrum around 60 GHz has raised the interest in designing gigabit Wireless Personal Area Networks (WPANs). Since at 60 GHz the signal attenuation is strong, this band is basically suitable for short range wireless ...
