A fast spherical harmonics transform algorithm
The spectral method with discrete spherical harmonics transform plays an important role in many applications. In spite of its advantages, the spherical harmonics transform has a drawback of high computational complexity, which is determined by that of the associated Legendre transform, and the direct computation requires time of O(N3) for cut-off frequency N . In this paper, we propose a fast a...
متن کاملA Fast Transform for Spherical Harmonics
Spherical Harmonics arise on the sphere S in the same way that the (Fourier) exponential functions {e}k∈Z arise on the circle. Spherical Harmonic series have many of the same wonderful properties as Fourier series, but have lacked one important thing: a numerically stable fast transform analogous to the Fast Fourier Transform. Without a fast transform, evaluating (or expanding in) Spherical Har...
متن کاملDiscrete fractional Fourier transform based on orthogonal projections
The continuous fractional Fourier transform (FRFT) performs a spectrum rotation of signal in the time–frequency plane, and it becomes an important tool for time-varying signal analysis. A discrete fractional Fourier transform has been recently developed by Santhanam and McClellan, but its results do not match those of the corresponding continuous fractional Fourier transforms. In this paper, we...
متن کاملOrthogonal radiation patterns for three-dimensional noise sources based on the spherical harmonics of sphere(s)
The control and thus sensing of radiation from three-dimensional noise sources has become a topic of strong interest as investigation moves away from the laboratory. Furthermore, the advance in signal processing power has facilitated the real-time fusion of a large number of sensor signals, which are typically required to give an accurate estimate of global error signals. Current state-of-the-a...
متن کاملAn Orthogonal Discrete Auditory Transform
An orthogonal discrete auditory transform (ODAT) from sound signal to spectrum is constructed by combining the auditory spreading matrix of Schroeder et al and the time one map of a discrete nonlocal Schrödinger equation. Thanks to the dispersive smoothing property of the Schrödinger evolution, ODAT spectrum is smoother than that of the discrete Fourier transform (DFT) consistent with human aud...
