What are the advantages of FFT algorithm?
The main advantage of an FFT is speed, which it gets by decreasing the number of calculations needed to analyze a waveform.
How does music algorithm work?
The basic idea of MUSIC algorithm is to conduct characteristic decomposition for the covariance matrix of any array output data, resulting in a signal subspace orthogonal with a noise subspace corresponding to the signal components.
