Relationships between two definitions of the discrete Wigner distribution and the continuous Wigner distribution

Digital Signal Processing
We present a very simple relationship between two widely used discrete-time discrete-frequency Wigner distributions. The first one is obtained through sampling and the second one is obtained from the representation theory of the finite Heisenberg group.

On the existence of discrete Wigner distributions

IEEE Signal Processing Letters, 1999
Among the myriad of time-frequency distributions, the Wigner distribution stands alone in satisfying many desirable mathematical properties. Attempts to extend definitions of the Wigner distribution to discrete signals have not been completely successful.

A unified definition for the discrete-time, discrete-frequency, and discrete-time/Frequency Wigner distributions

IEEE Transactions on Acoustics, Speech, and Signal Processing, 1986
Various discrete definitions of the Wigner distribution (WD) for discrete-time signals have been proposed in previous works. The formulation developed in this paper leads to natural and unified definitions of discrete versions of the WD. They are directly related to the continuous and preserve most of its properties.

The aliasing problem in discrete-time Wigner distributions

IEEE Transactions on Acoustics, Speech, and Signal Processing, 1983
The Wigner distribution (WD) is a bilinear mapping that, with some restrictions, can be interpreted as the energy distribution of a signal over time and frequency. This makes the WD useful in signal analysis, but its actual use requires a discrete-time version. It is shown that the bilinear nature of such a discrete time WD causes aliasing problems. It
