Abstract:A time varying impulse response for low voltage power network channel is developed. Based on the theory of linear system, the propagation mode of electromagnetic wave in the power network is analyzed and the characteristics of signal multi path propagation is used to deduce the time varying impulse response of the low voltage power network channel. Then the impulse response is discretized according to the limitation resolution of physical communication system, which is beneficial to both of measurements and computer simulations.
