An Instantaneous Frequency Identification Algorithm for Time-Varying Frequency Signals
A high-precision instantaneous frequency (IF) identification algorithm is proposed in this paper. The algorithm is based on the relationship between the signal phase and time, and uses Taylor's expansion to parameterize the time-varying frequency. It can accurately identify the IF of various fr...
