The Wigner Distribution of a Linear Signal Space
For many good reasons, the WD of a signal is often considered as the “central” quadratic TF signal representation with energetic interpretation. This exceptional role of the WD is maintained when the WD is extended to linear signal spaces, which explains why the WD is being emphasized in this work.
