    摘要: The invention provides a method and an arrangement which allow avoidance of significant degradation in performance of a broadband system receiver or even blocking of the receiver, caused by simultaneous use of the same frequency or simultaneous use of adjacent frequencies by a narrowband and a broadband communications systems, or background noise peaks produced by a plurality of various man-made interference signals. In one invention embodiment, the energy of the received signal is determined in narrower sub-bands, the average of the sub-band signal energies is calculated, the energies of the sub-band signals are compared with said average and if any of the sub-band signal energies exceeds the average by a predetermined threshold value, interference is cancelled by a tunable band-stop filter.
