APPARATUS AND METHOD OF MULTIPLE ANTENNA TRANSMITTER BEAMFORMING OF HIGH DATA RATE WIDEBAND PACKETIZED WIRELESS COMMUNICATION SIGNALS |
摘要 |
The present invention provides an apparatus and method of multiple antenna transmitter beamforming of high data rate wideband packetized wireless communication signals, where each of the signals comprises N frequencies, where N is a positive integer. The apparatus, in an exemplary embodiment, includes (1) a transmit beamformer (220) that co-phases and weights the signals for each of the N frequencies across M antennas, thereby generating M co-phased and weighted frequency data and M Inverse Fast Fourier Transform units (IFFTs 230, 232) that convert the M co-phased and weighted frequency data into M digital outputs, and M transmit antennas (260, 262) transmitting the M co-phased and weighted signals, where M is an integer greater than or equal to 2.
