摘要: Antenna weights for a transmit path (3) between two communication devices (1, 2), the first device (1) having an antenna array (4, 5, 6) are generated in second (2) and fed back to weighting circuitry (9, 10, 11, 12) (1). The invention is particularly applicable multicarrier systems such as OFDM systems. Only those sub--carriers identified being received with comparatively poor signal quality calculated (1), thus limiting additional overhead requirements minimum.
