1. In a base transmitter, a method for communicating with one or more remote stations within a system utilizing frequency division duplexing (FDD), the method comprising:

  • receiving baseband tone data comprising multiple discrete frequency tones;

    deriving a matrix of spatial weights composed of weight vectors corresponding to each of the one or more remote stations; and

    multiplying the baseband tone data by the derived matrix of spatial weights to produce weighted tone data for transmission to the one or more remote stations via a forward link channel.
