What is the term used to refer to the condition where the signals from a very strong station are superimposed on other signals being received?

Cross-modulation interference happens when a very strong signal drives the receiver into nonlinearity, causing the strong signal to modulate or imprint its variations onto other signals being received. In other words, the strong signal’s amplitude and phase variations leak into the paths of weaker signals, so you hear the weak signals with the strong one’s modulation superimposed on them. The other terms don’t describe this situation as precisely: intermodulation distortion is about creating new frequencies from nonlinear mixing of signals, capture effect is the stronger signal taking over and suppressing the weaker, and receiver quieting refers to changes in perceived noise or volume rather than modulation of one signal by another.
