Patent ID: 8081722

Claim:
A communications device, comprising: a signal input for receiving both wideband and in-band, narrowband communications signals having wideband communications data that is transmitted over a wideband communications channel and narrowband communications data that is transmitted within an in-band, narrowband communications channel over the same wideband communications channel; a circuit that splits the communications signals into a wideband signal channel and narrowband signal channel; a narrowband filter within the wideband signal channel that filters the wideband communications signal and removes any narrowband communications signals, said narrowband filter comprising an adaptive filter circuit having a plurality of non-adaptive and adaptive filter taps with weighted coefficients and a circuit configured to select the number and order of adaptive filter taps based on one of at least measured output power from the adaptive filter and signal modulation; a demodulator within the wideband signal channel that demodulates the filtered wideband communications signal to obtain any wideband communications data; and an in-band, narrowband demodulator within the narrowband signal channel that demodulates the narrowband communications signals to obtain any narrowband communications data.
