System and Method of Adaptive Out-of-Band Interference Cancellation for Coexistence

摘要

Adaptive cancellation of out-of-band interference between coexisting wireless communication devices. A signal including out-of-band noise may be received by a victim communication device and by an adaptive cancellation device. The adaptive cancellation device may use an adaptive filter to isolate a representation of the out-of-band noise. The adaptive cancellation device may then subtract the noise from the receive path of the victim communication device. The victim device and the adaptive cancellation device need not be located on the same chip as an aggressor device generating the out-of-band noise.
