- Title:
- Wideband Direction-of-Arrival Estimation Using Frequency-Domain Frequency-Invariant Beamformers: An Analysis of Performance
- Abstract:
- This paper presents an extension of the wideband direction-of-arrival estimation method using frequency-domain frequency-invariant beamformers (Do-Hong et al., 2003) with an analysis of performance. An asymptotic expression for the root-mean-square error and a resolution threshold of signal-to-noise-ratio for resolving directions of sources are shown. A comparison of analysis and simulation as well as numerical results are also presented.
