Dynamic filtering to suppress interference from adjacent channels

摘要

FIELD: physics.;SUBSTANCE: method for adjacent channel interference suppression comprises steps of receiving a composite signal including a useful signal and possibly one or more adjacent channel interferers, measuring the useful signal and the possibly one or more adjacent channel interferers, and adjusting the location of at least one dynamic filter to extract the useful signal. A receiver apparatus comprises an antenna configured to receive a composite signal including a useful signal and possibly one or more adjacent channel interferers, an interference measurement circuit configured to measure the useful signal and the possibly one or more adjacent channel interferers, at least one dynamic filter configured to extract the useful signal, and a processor configured to adjust the location of at least one dynamic filter to extract said useful signal.;EFFECT: possibility of optimum interference suppression with minimum level of undesirable suppression of the useful signal.;37 cl, 10 dwg
