FREQUENCY TRANSFORMATION BASED TRANSMIT BEAMFORMING IN A COMMUNICATION SYSTEM |
摘要 |
The present invention provides a system and method for transmit beamforming in a Frequency Division Duplex communication system. A first step (600) includes correcting for differences between transceiver receive and transmit responses within a base station. A next step (604) obtaining a beamforming weight of a phase antenna array on an uplink. A next step (606) transforming the uplink beamforming weight a downlink beamforming weight by applying a phase correction that is a function of wavelength at the uplink and downlink frequencies and distance between antenna elements.
