Patent ID: 7184492

Claim:
A method of transmitting an information signal to a first mobile terminal comprising: forming a plurality of directional beams, each directional beam oriented in a different direction and having a propagation delay; selecting two or more directional beams to use for transmitting the information signal to the first mobile terminal; for each selected directional beam, generating a transmit signal derived from the information signal for transmission to the first mobile terminal; transmitting the transmit signals to the first mobile terminal over respective ones of the selected directional beams; and compensating for differences in propagation delay between the selected directional beams such that the transmit signals arrive time aligned at the first mobile terminal; wherein compensating for differences in propagation delay between the selected directional beams comprises delaying transmit signals transmitted on at least one of the selected directional beams; and, wherein forming a transmit signal for a selected directional beam comprises: determining a channel coefficient polynomial describing the estimated amplitude and phase attenuation associated with the selected directional beam; and prefiltering the information signal using the channel coefficient polynomial.
