1. A method for allocating a plurality of RAKE branches in a radio system, the method comprising:
- allocating the RAKE branches to receive a plurality of transmitted signals based on a plurality of impulse responses;
receiving, at the RAKE branches of a receiver, the signals at different polarization levels; and
weighting the impulse responses of the signals received at the different polarization levels by a plurality of values describing a signal quality for optimizing the allocating.

Abstract
The present invention relates to a method for allocating RAKE branches and a RAKE receiver. The solution is used in a radio system where a transmitter transmits a signal to a receiver comprising RAKE branches which receive the signal at different polarization levels. The RAKE branches are allocated to receive the signal on the basis of an impulse response, and in which method the impulse responses of the signals received at different polarization levels are weighted by values describing signal quality for optimizing allocation.
