Abstract
An interference cancellation system supports a dynamic operating range from maximum interfering signal level to the on-channel noise floor. The system uses a novel combination of analog and digital processing effectively cancelling 1) high-level interfering signal components, 2) low-level interfering noise, and 3) distortion components. The system employs an interrelated combination of cross-domain analog and digital processing techniques to defeat the inherent dynamic range limitations existing in either individual domain.
