Undirected graphs: is the shift-enabled condition trivial or necessary?
Liyan Chen, Samuel Cheng, Kanghang He +2
It has recently been shown that, contrary to the wide belief that a shift-enabled condition (necessary for any shift-invariant filter to be representable by a graph shift matrix) c…

Shift-enabled graphs: Graphs where shift-invariant filters are representable as polynomials of shift operations
Liyan Chen, Samuel Cheng, Vlandimir Stankovic +1
In digital signal processing, shift-invariant filters can be represented as a polynomial expansion of a shift operation,that is, the Z-transform representation. When extended to gr…
