Abstract
A method for estimating a channel from received signals transmitted via the channel, includes the steps of receiving the received signals with receiving sensors of a receiving device. The received signals are composed of a plurality of subscriber signals. The subscriber signals are marked with transmitter-specific fine structures. A subscriber signal of the plurality of subscriber signals is transmitted by a plurality of wave elements having differing incidence directions at a receiving point. An incidence direction of at least one of the wave elements is obtained in the receiving device. Directionally selective channel impulse responses are determined from the plurality of received signals and the incidence direction of the at least one wave element.
