摘要： A system and method are described for distributed antenna wireless communications. For example, a method implemented within a wireless transmission system comprised of a plurality of wireless client devices and a plurality of distributed antennas is described comprising: computing channel state information (CSI) for wireless communication channels between the plurality of base distributed antennas and the wireless client devices; computing precoding weights from the channel state information; precoding data using the precoding weights prior to wireless transmission from the plurality of distributed antennas to the wireless client devices; and wirelessly transmitting the precoded data from the distributed antennas to each of the wireless client devices, wherein the precoding causes radio frequency interference between the plurality of base stations but simultaneously generating a plurality of non-interfering radio frequency user channels between the plurality of distributed antennas and the plurality of wireless client devices.

摘要： Systems and methods are described for radio frequency (RF) calibration in a multiple antenna system (MAS) with multi-user (MU) transmissions (“MU-MAS”) exploiting uplink/downlink channel reciprocity. The RF calibration is used to compute open-loop downlink precoder based on uplink channel estimates, thereby avoiding feedback overhead for channel state information as in closed-loop schemes. For example, a MU-MAS of one embodiment comprises a wireless cellular network with one or multiple beacon stations, multiple client devices and multiple distributed antennas operating cooperatively via precoding methods to eliminate inter-client interference and increase network capacity.

摘要： A system and method to reduce the number of active targeted viruses, bacteria or other microbes or microorganisms within an indoor or outdoor space using an array of radio frequency antennas, lasers or acoustic emitters is presented. The system sweeps through a series of beam patterns. The radio, laser or acoustic frequency and dwell time depend on the targeted viruses and bacteria. By sweeping through a wide range of transmit beamforming vectors, it is possible to kill or render harmless microbes or microorganisms at many locations throughout the coverage area while avoiding exposing humans to harmful levels of radio frequency or laser power. The proposed system and method can be flexibly applied to many array geometries including those with large spacing and non-isotropic antennas or acoustic emitters, as well to a variety of type of lasers.

摘要： Systems and methods are described for enhancing the channel spatial diversity in a multiple antenna system (MAS) with multi-user (MU) transmissions (“MU-MAS”), by exploiting channel selectivity indicators. The proposed methods are: i) antenna selection; ii) user selection; iii) transmit power balancing. All three methods, or any combination of those, are shown to provide significant performance gains in DIDO systems in practical propagation scenarios.
