Embed:: an effective method of beamforming deconvolution. Embedded is a small matlab package that comes with magazine papers: lylloff, Oliver, evron Fernandez Grande, Elizabeth Tina roeger, Finn agerkvist, Martin S. Anderson and jorhald. "Improve the efficiency of deconvolution algorithm for sound source location." The package contains two folders: Src / - fftnnls. M: fft-nnls algorithm - fista. M: fista algorithm - NNLS. M: NNLS problem, f (x) = 1 / 2 * | ax-b||_ 2 ^ 2 - zeropad. M: pre deconvolution process zeropads array, for example / - beamformer_ Setup. M: set the size and opening angle of the grid, SNR - PSF. M: calculate the point spread function - deconv. M: set the deconvolution algorithm, the number of iterations and zeropadding- micarray.mat : the - run of microphone array coordinates (x, y)_ Example. M: run example and plot result usage: add Src / for path and run_ example.m
