Sayeed, "A Canonical Covariance Based Method for Generalized Joint Signal Representations," <i>IEEE Signal Processing Letters,</i> 1996.https://hdl.handle.net/1911/19986Journal PaperGeneralized joint signal representations extend the scope of joint time-frequency representations to a richer class of nonstationary signals. Cohen's marginal-based generalized approach is canonical from a distributional viewpoint, whereas, in some other applications, for example, in a signal detection framework, a covariance-based formulation is needed and/or more attractive. In this note, we present a canonical covariance-based recipe for generating generalized joint signal representations. The method is highlighted by its simple characterization and interpretation, and naturally extends the concept of the corresponding linear representations.engjoint signal representationsTime Frequency and Spectral AnalysisJournal articlejoint signal representationshttp://dx.doi.org/10.1109/97.489067
