Using a sliding data window, the STFT can obtain the time frequency characteristic of discretional spot.
In order to locate the interference spot in time frequency domain, good temporal and spectral resolutions are necessary.
The time frequency
distribution of the received signal is subjected to image processing techniques in order to identify transmission parameters of the primary user as displayed in Figure 1.
7) showed in their pilot study that the time frequency
distribution patterns of QRS complex calculated by wavelet analysis did not vary significantly from beat to beat during good signal quality.
