The invention relates to a measuring method and a receiver. An array
antenna is used for measuring the spatial colour of received
interference. Using the spatial colour measurement result, an
interference detector (217) controls a method to be used for combining
the signals received by the different antenna elements (200 202).
Monitoring devices (219) are used, in turn, for monitoring the spatial
colour of the interference and for taking into account the result of the
colour measurement for enhancing the operation of a radio system.
