Time-Frequency Analysis Tool - Radial Gaussian Kernel Time-Frequency Distribution
Time-Frequency Analysis Tool - Radial Gaussian Kernel Time-Frequency Distribution. To eliminate cross-terms in the time-frequency distribution plane, mutual components must be effectively removed while retaining auto-components in the ambiguity function domain. This can be achieved by designing a kernel function matched to the signal's characteristics. The signal-adaptive radial Gaussian kernel time-frequency distribution provides an optimal representation for time-frequency analysis with minimal interference components.
