文摘

•: It is possible to transform non-stationary signals into stationary signals.
•: A new class of generalized angular deterministic (GAD) signals is proposed.
•: A new transformation based on normalization is proposed.
•: A new model of harmonic components under varying regime is proposed.
•: Method is illustrated on well-known DRS algorithm.
•: Normalization extends dealing with variable frequency to variable frequency and amplitude.
