Abstract
The invention relates to a diversity combining method and to a receiver. In diversity combining, outputs ( ) of a matched filter ( ) of each branch are weighted with a quality estimate ( ) which is generated in quality means ( ) in such a matter that the quality estimate ( ) is proportional to the inverse of the interference strength ( ) of the signal. The strength ( ) of signal interference is generated in interference means ( ) e.g. in variance-like fashion from the differences between a reference signal ( ) generated in reference signal means ( ) as the convolution of the estimated channel impulse response and the predetermined sequence and a signal received from the channel.
