Abstract

An interfering signal from a co-running modem is filtered using a notch filter to cancel high frequency harmonic interference to a received radio frequency (RF) signal. Thereafter, a metric scaling and tone nulling are performed in the received RF signal to further eliminate residual harmonic frequencies.
