ABSTRACT:
The present invention seeks to estimate a dedicated channel of the downlink transmission from a base station (BS) to a subscriber station (MS) in a mobile radio communications system with antenna diversity. To this end, the subscriber station (MS) calculates a first estimation of the dedicated channel from an estimation of a global channel (CPICH) while using a weighting vector (W, W′) used by the base station (BS) for the beam forming of the dedicated channel.
