Abstract: An adaptive electromagnetic wave canceling system and method for canceling an electromagnetic interference (EMI) signal generated from an EMI signal source, from a broadband signal being received by a receiver. In one implementation an adaptive canceller subsystem is used that directly receives the EMI signal and a sample of the broadband signal, in which the sample includes an EMI signal component. A time delay stage is incorporated to delay the broadband signal before it is received by the receiver. The adaptive canceller subsystem generates a correction signal that is an inverse of the EMI signal component. The correction signal is applied to the broadband signal to effectively cancel the EMI signal component therefrom before the broadband signal is received by the receiver. In one implementation an automatic gain control is implemented that automatically adjusts the adaptive canceller subsystem to a level of the sample broadband signal, to thus form a closed loop EMI canceling system.
