Abstract
A processing device tracks a frequency hopping sequence implemented by a personal area network (PAN) transmitter in a user device and identifies a set of filter coefficients corresponding to a first frequency of a plurality of frequencies in the frequency hopping sequence, wherein the PAN transmitter is currently transmitting a PAN signal at the first frequency. The processing device configures a tunable notch filter with the set of filter coefficients to cause the filter to remove at least a portion of a PAN component at the current frequency from a combined signal received at a wireless local area network (WLAN) receiver in the user device, the combined signal comprising a WLAN component attributable to a received WLAN signal and the PAN component attributable to the PAN signal.
