Abstract: A method and apparatus for a method and apparatus for correlation canceller for interference mitigation with adaptive DC offset cancellation for a dual mode communication device includes detecting an active signal transmitting in one mode; configuring integrators associated with the adaptive correlation canceller into gain amplifiers; detecting DC offset utilizing the gain amplifiers and comparators; and configuring the integrators from the gain amplifiers back to integrators with the DC offset applied thereto. The active signal transmitting in one mode can be Long Term Evolution (LTE) which is adjacent to a signal in another mode.
