Patent ID: 7853195

Claim:
An adaptive canceller system for canceling an electromagnetic interference (EMI) signal component generated from an EMI signal source, from a broadband signal being, wherein the broadband signal and EMI signal component are received together via an antenna feeding a receiver, said system comprising: an adaptive canceller subsystem including: an adaptive processor having first and second inputs, and an output, the output of the adaptive processor representing a set of control inputs; a filter having a first input for receiving the EMI signal, and a second input for receiving the set of control inputs for configuring the filter; a time delay stage having an input for receiving said broadband signal and producing a delayed broadband signal, and an output in communication with an input of said receiver; said first input of said adaptive processor adapted to receive said EMI signal and said second input of the adaptive processor adapted to receive a sample of said delayed broadband signal, and the adaptive processor using the EMI signal and the broadband signal to generate the set of control inputs for the filter, the filter using the control inputs to generate a correction signal that is an inverse of said EMI signal component, and that is applied to said input of said receiver to cancel said EMI signal component from said broadband signal.
