ABSTRACT:
Influencing the transmission of signals from a transmitting device to a receiving device in a communication system comprising at least one transmitting device and at least one receiving device is disclosed. In a receiving station received transmission signals are processed and a feedback signal to be transmitted to a transmitting device is generated on the basis of the processed signals. Then, transmit weights to be applied to transmission signals are determined in accordance with the feedback signal.
