A controlled interference-avoidance, band-rejection filtering mechanism is installable in a direct sequence spread spectrum communication device (e.g., a DSSS radio). This controlled filtering mechanism monitors a potentially interfering frequency-hopping spread spectrum (FHSS) transmitter, to identify one or more frequencies to which the FHSS transmitter is expected to hop during a communication interval of the DSSS communication device. Based upon this frequency-hopping information, one or more spectral notches are programmed into the passband spectrum of a DSSS band-rejection filter, so as to exclude the potentially interfering frequencies from DSSS communication signals employed by the DSSS communication device during its communication interval.
