Abstract:
Embodiments include systems and methods for managing an adaptive interference filter performed by a device processor of a mobile communication device. A device processor may determine whether a transmission power from the mobile communication device is greater than or equal to a transmit power threshold. The device processor may determine whether a ratio of interference in a received signal to a level of the received signal including noise (interference ratio) is greater than or equal to an interference ratio threshold in response to determining that the transmission power is greater than or equal to the transmit power threshold. The device processor may perform interference cancellation with the adaptive interference filter in response to determining that the interference ratio is greater than or equal to the interference ratio threshold. In some embodiments the adaptive interference filter may be a non-linear interference cancellation filter.
