Diversity combining method, and receiver

摘要

The invention relates to a diversity combining method and to a receiver. In diversity combining, outputs (33) of a matched filter (25) of each branch are weighted with a quality estimate (32) which is generated in quality means (28b) in such a matter that the quality estimate (30) is proportional to the inverse of the interference strength (31) of the signal. The strength (31) of signal interference is generated in interference means (28c) e.g. in variance-like fashion from the differences between a reference signal (30) generated in reference signal means (28a) as the convolution of the estimated channel impulse response and the predetermined sequence and a signal received from the channel.
