Boaz Rafaely Fundamentals of Spherical Array Processing

This is a collection MATLAB routines that perform array processingtechniques on spatially transformed signals, commonly captured witha spherical microphone array. The routines fall into four maincategories: 1. obtain spherical harmonic (SH) signals with broadband characteristics,as much as possible, 2. … See more The first operation is to obtain the SH signals from the microphonesignals. That corresponds to two operations: a matrixing of the signalsthat performs a discrete spherical harmonic transform (SHT) on thesound … See more After the SH signals have been obtained, it is possible to performbeamforming on the SHD. In the frequency band that the SH signals areclose to … See more Contrary to the fixed beamformers of the previous section, parametric andsignal-dependent beamformers use information about the signals … See more WebIn this paper, a high-precision, low-cost, batch processing nanoimprint method is proposed to process a spherical microlens array (MLA).
