摘要： In a RF communications system, aspects for single weight antenna system for HSDPA may comprise receiving HSDPA signals via a plurality of receive antennas and individually adjusting a phase of a portion of the received HSDPA signals via a single weight. The phase adjusted portion of the received HSDPA signals may be combined with at least one of the received HSDPA signals to generate combined HSDPA signals. At least one control signal may control the adjusting of the phase of the received HSDPA signals. Discrete phases may be communicated to adjust the phase of the portion of the received HSDPA signals, where the plurality of the discrete phases may range from zero radians to substantially 2π radians. Phase shift channel estimates may be generated during the identified time to determine the discrete phase. A desired phase may be generated from the phase shift channel estimates, and the single weight may be generated from the desired phase.
