Zusammenfassung:PROBLEM TO BE SOLVED: To remove or compensate for radio interference that become a severe fault for a receiver capable of appropriately receiving a transmission data signal. SOLUTION: Disclosed are radio frequency (RF) interference cancellation techniques that effectively estimate RF interference to data signals being received using a frequency domain model, and then remove the estimated RF interference from the received data signals. Improved techniques for digitally filtering multi-carrier modulation samples to reduce sidelobe interference due to the RF interference are also disclosed. COPYRIGHT: (C)2007,JPO&INPIT
