  • Publication number: 20220255572
    Abstract: A system for distributed phased array multiple input multiple output (DPA-MIMO) communications is disclosed. The system includes beamforming (BF) modules. Each BF module comprises a beamforming antenna, a downconverter that downconverts a beamformed antenna radio frequency signal to an intermediate frequency signal, and an upconverter that upconverts an intermediate frequency signal to a radio frequency signal and sends said radio frequency signal to said beamforming antenna for transmission. The system further includes intermediate frequency (IF) radios. Each IF radio comprises a downconverter that downconverts an intermediate frequency signal sent from a BF module to a baseband signal, and an upconverter that upconverts said baseband signal to an intermediate frequency signal that is transmitted to a beamforming module.

  • Publication number: 20070025420
    Abstract: A method of transmitting information on ultra-bandwidth systems is provided. The method can double the data rate of existing methods. The method comprises sending and receiving an ultra-wideband pulse. The ultra-wideband pulse comprises at least a dual pulse (two sub-pulses) of time Tw and is sent during a frame interval of time Tf. The sub-pulses are sent repeatedly, and Tf is larger than Tw. The method can permit multipath energy collection, simple timing acquisition, simple implementation and robustness.
