Sinusoids remain the prototypical waveform for signal modeling, analysis, detection, and estimation in stationary environments, but are unsuitable for the analysis of signals with non stationary frequency content. In [1], the MA-CDFRFT was introduced as a useful tool for the analysis of multicomponent chirp signals in the absence of noise. Subspace approaches derived from a eigenvalue decomposition of the correlation matrix of noisy observations of sinusoidal signals, such as the MUSIC or… CONTINUE READING
