Abstract
A stationary interference cancellor utilizes a programmable digital signal processor with cancelling software to provide the required combinations of time delay and filtering to perform interference cancelling. The digital signal processor continually analyzes the information spectrum and builds cancellation filters around stationary undesirable signals. By reducing the size of the delay and by adding an FIR shaping filter and automatic gain control at the output of the circuitry, interference cancelling performance is greatly improved.
