ABSTRACT:
A mobile user receiver having a cancellation system for removing selected signals from a traffic signal prior to decoding includes a receiver having a system input for receiving communication signals from a transmitter over an air interface. The system input is supplied to a traffic signal cancellation system for canceling unwanted traffic signals. The system input is also supplied to a pilot signal cancellation system for removing a global pilot signal. The output of the pilot signal cancellation system is subtracted from the output of the traffic signal cancellation system to provide a cancellation system output free from unwanted traffic signals and the global pilot signal.
