Abstract
A new relation between the Wigner distribution (WD) and the short-time Fourier transform (STFT) is given in this paper. Based on this relation, we interpreted the time-frequency resolution, producing and distributing the cross terms of the WD in the view of the windows of STFT. It is concluded that by sagaciously choosing the windows of STFT, we can achieve a higher resolution than the WD. The theoretical analysis is confirmed by computer simulation results
