A Volterra Series Description of Crosstalk Interference in Communications Systems

Crosstalk interference is an important consideration in transmission system engineering. 1 It is defined 2 as the disturbance created in one (desired) communications channel* by the signals in another (interfering) communications channel. Crosstalk is classified as due to interchannel or intrachannel effects and may be of either intelligible or unintelligible type. Interchannel crosstalk occurs between two different communications channels as, for example, when the transmitted signals of an interfering channel pass through the channel selectivity filters of f Here "channels" refer to different communications paths (which are distinguished by, e.g., different frequency bands or different physical transmission media) together with the receivers associated with each of these paths.
