SELF-INTERFERENCE CANCELLATION USING DIGITAL FILTER AND AUXILIARY RECEIVER |
摘要 |
Aspects of the disclosure are directed to interference cancellation. A method of performing interference cancellation in a wireless device having a transmitter and a receiver includes enabling a radio frequency (RF) receive filter for a victim band from a plurality of RF receive filters in a receive path; measuring an RF filter characteristic of the enabled RF receive filter with an auxiliary receiver; configuring a programmable digital filter to match a filter characteristic to the measured RF filter characteristic to yield a reference signal; and providing the reference signal to the receive path for interference cancellation; and, the reference signal is subtracted from a receive signal in the receive path. |
