We investigate nonstationary disturbances in wireline and wireless systems. In wireline, we make us of the common-mode signal to cancel impulse noise from the differential mode or use the common mode to forecast error positions.

In wireless, we model impulse noise on antenna arrays caused by ignition, electrical machines, MRI equipment, and alike. Furthermore, we determine detection and decoding schemes under impulse noise.
