Abstract
For transmitter-side processing of information it is decided in which direction of transmission signals for a receiver are to be transmitted, the direction of transmission being a linear combination of one of a number of antenna directional diagrams corresponding to a first plurality. In a baseband processing section (REC), a number of antenna directional diagram signal sequences (X(),X()), corresponding to the first plurality is determined from a signal sequence (T), determined for the receiver by weighting of the signal sequence (T) for each of the antenna directional diagrams with a coefficient (a(), a()) corresponding to each of the linear combinations. Each antenna directional diagram signal sequence (X(),X()) is transmitted by a dedicated logical connection from the baseband processing section (REC) to a high frequency processing section (RE). A conversion of the first plurality of antenna directional diagram signal sequences (X(),X()) to a number of antenna element analogue signals, corresponding to a second plurality different to the first plurality, is carried out in the frequency processing section (RE). Each antenna element analogue signal is transmitted from one antenna element (A) of a number of antenna elements (A) corresponding to the second plurality.
