Time S transformTime inverse S transformtime-frequency filteringThe Linear Frequency Modulation (LFM) signal is a classical non-stationary random signal. And the processing method to LFM must expand from frequency domain to time-frequency domain. The S transform (ST) is a time-frequency analysis ...
We will show that time-frequency filtering can be used to estimate |H (t,ω)|2, a technique that is essentially a two-dimensional generalization of straight-forward, stationary methods. Further, we will see that |H(t, ω)|2 is closely related to the time-frequency representations of the...
