Abstract
A signal processing device for a diversity combining radio receiver is disclosed. Said device comprises a plurality of receive branches and a joint detector adapted to determine a joint received symbol based on a combined signal. Said device also comprises a control unit adapted to determine a branch signal error based on the joint received symbol and the input signal of that receive branch. Each receive branch further comprises an adaptive filter. The control unit is adapted to update the coefficients of the adaptive filter of each receive branch based on a weighted signal error combination, wherein weight of the weighted signal error combination is selected based on channel conditions. A corresponding diversity combining radio receiver, a corresponding electronic apparatus, a corresponding method, a corresponding computer program product, and a corresponding computer readable medium are also disclosed.
