Abstract EN
The short-time Fourier transform (STFT) is a classical tool, used for characterizing the time varying signals.
The limitation of the STFT is its fixed time-frequency resolution.
Thus, an enhanced version of the STFT, which is based on the cross-level sampling, is devised.
It can adapt the sampling frequency and the window function length by following the input signal local characteristics.
Therefore, it provides an adaptive resolution time-frequency representation of the input signal.
The computational complexity of the proposed STFT is deduced and compared to the classical one.
The results show a significant gain of the computational efficiency and hence of the processing power.
