Abstract
A device to cancel noise in broadcast signal is disclosed. The device a first port to connect to a main antenna, a second port to connect to a noise antenna, a processor coupled to the first port and the second port to measure the broadcast signal received at the first port and a noise signal received at the second port to derive a first set of coefficients, a first adaptive filter coupled to the first port and the processor and a second adaptive filter coupled to the second port and the processor. The first adaptive filter and the second adaptive filters are configurable based on the first set of coefficients to remove the high energy parts of a frequency spectrum of signals received at the first port and the second ports respectively. The device also includes a subtraction coefficient calculator module coupled to the first filter and the second filter to derive a second set of coefficients and a subtractor coupled to the first port, the second port and the subtraction coefficient calculator module to subtract the noise signal from the broadcast signal.
