  • Patent number: 10361733
    Abstract: Various embodiments disclosed herein provide for a low complexity transmitter structure for active antenna arrays by reducing the number of digital predistortion extraction loops that need to be performed. Digital predistortion (DPD) corrects any non-linearities in a power amplifier. By determining which power amplifiers have similar characteristics in an array, and thus may use similar predistortion coefficients, once the DPD coefficients are determine for one of the grouped power amplifiers, DPD can be performed on each of the grouped power amplifiers based on the DPD coefficients.

  • Patent number: 10283834
    Abstract: The present invention is directed to methods and apparatuses for beamforming signals or compute beamformed signals. The present approach is to determine a series of beams from or for a set of devices configured for receiving signals from and/or transmitting signals to one or more regions of interest in an n-dimensional space, with n=2 or 3. Each of the devices has a known position pi within said n-dimensional space. Signals are to be respectively transmitted or received non-uniformly in this space, i.e., according to the particular regions of interest. During a first phase, operations are performed in order to successively obtain a spatial filter function {circumflex over (?)}(r), a beamforming function ?(p), and beamforming weights ?(pi). The spatial filter function {circumflex over (?)}(r) matches projections of the regions of interest onto an n?1-dimensional sphere centered on said set of devices.

  • Patent number: 10263329
    Abstract: Embodiments for providing dynamic azimuth scanning are generally described herein. In some embodiments, weather survey measurements are performed to estimate environmental losses as a function of azimuth angles. Gain improvements are determined based on the amount of energy increase used at different azimuth angles derived from the azimuth loss survey measurements. A gain profile is generated based on the determined gain improvements. An azimuth offset profile is derived using the gain profile to define azimuth angles where progressive scan back is used in the area of environmental losses to provide additional power and to define azimuth angles where progressive scan forward is used in regions of low loss. Dynamic electronic azimuth beam steering provides a near-constant average target detection range as a function of azimuth in the presence of non-uniform loss.

  • Patent number: 10018715
    Abstract: A radar sensor for vehicles, including a group antenna, having a linear array of antenna elements, a feed unit for feeding transmission signals having a settable phase relationship into the antenna elements, a control unit controlling the feed unit, and an evaluation device evaluating received radar echoes and angle-resolving locating of objects. The group antenna includes at least two non-interleaved subgroups, the feed unit supplies in-phase transmission signals to the elements, while the transmission signals for the various subgroups have a settable phase difference, the control unit periodically changes the settable phase difference so that the transmission signals have a base phase difference in one measuring cycle and a phase difference in another measuring cycle which differs by a fixed absolute value from the base difference. The control unit sets the base difference based on levels of the received radar echoes to maximize the level difference between the measuring cycles.
