Method and apparatus for calculation of path weights in a RAKE receiver

摘要

A method for calculation of path weights for the equalization of a data signal that is transmitted via a data channel whose power is regulated in a RAKE receiver is disclosed. In the method, at least one uncorrected path weight is calculated for the data signal that is transmitted via the data channel, using channel estimation results that have been obtained on the basis of a common pilot channel. The uncorrected path weight is corrected by multiplying it by a correction factor that contains a ratio of a data-channel-specific gain estimation to a pilot-channel-based gain estimation.
