High-resolution methods are generally defined to be high-performance methods for estimating and/or detecting the desired and/or undesired signal components present in a given set of data. The term “high-resolution” also implies a good ability to resolve very “similar” signal components. One of the most common problems in signal processing is known as frequency estimation. In frequency estimatio...

The emerging applications of the parametric loudspeaker, such as 3D audio playback systems, require both controllable directivity and high fidelity at the audible frequency (a.k.a. the difference frequency). Although phased array techniques have been applied and proven adequate to steer the mainlobe of a parametric loudspeaker, and preprocessing methods have been studied to reduce the harmonic ...
