    摘要: A receiver in a radio system, comprising one or more antennas (600A to 600B) for receiving a signal including signal components descriptive of a signal to be detected and an interfering signal. The receiver comprises means for measuring (614A to 614B) the antenna-specific reception power of the received signal and means for weighting (614A to 614B) the signal received in each antenna by a antenna-specific weighting coefficient proportional to the reception power of said signal.

    摘要: An arrangement for cancelling interference from a received signal, comprising: a first radio system and a second radio system employing a time slot structure in data transmission and operating on at least partly the same geographical area as the first radio system. A receiver of the first radio system is configured to control the cancellation of interference from the received signal on the basis of the timing employed in the time slot structure of the second radio system.

    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.
