Ukraine said the drones it used in its major attack on Russia used AI when they lost signal. The drones used AI to move along a pre-planned route, and their warheads were automatically activated.

A time-frequency representation of linear signal spaces, called its Wigner distribution (WD), is introduced. Similar to the WD of a signal, the WD of a linear signal space describes the space's energy ...

For many practical applications in wireless communications, we need to recover a structured sparse signal from a linear observation model with dynamic grid parameters in the sensing matrix.
