Patent ID: 7751465

Claim:
A method for removing an unwanted traffic signal and a global pilot signal from a received signal prior to decoding, the method comprising: receiving code division multiple access (CDMA) communication signals from a transmitter over an air interface, the communication signals including a desired traffic signal, an unwanted traffic signal, and a global pilot signal, the unwanted traffic signal being spread with an unwanted traffic code and the global pilot signal being spread with a pilot signal code; inputting the received communication signals to a traffic signal canceller configured to cancel a cross-correlation of an unwanted traffic signal and the desired traffic signal, thereby producing a traffic signal canceller output (O); inputting the received communication signals to a pilot signal canceller configured to produce a pilot signal canceller output for removing a cross-correlation of the global pilot signal and the desired traffic signal; and subtracting the pilot signal canceller output from the traffic signal canceller output.
