  • Patent number: 10310491
    Abstract: Various embodiments are described that relate to a radiating element and an engineered magnetic material. In a communication environment a radiating element can be used to communicate information, such as to send signals. Various factors, including electromagnetic factors, can influence the performance of the radiating element. In one example, if the radiating element becomes too close to a ground plane, then performance of the radiating element can suffer. To counter negative effects of being too close to the ground plane an engineered magnetic material can be employed that causes the radiating element to perform better when relatively close to the ground plane.

  • Patent number: 10313000
    Abstract: Methods and systems are described for providing end-to-end beamforming. For example, end-to-end beamforming systems include end-to-end relays and ground networks to provide communications to user terminals located in user beam coverage areas. The ground segment can include geographically distributed access nodes and a central processing system. Return uplink signals, transmitted from the user terminals, have multipath induced by a plurality of receive/transmit signal paths in the end to end relay and are relayed to the ground network. The ground network, using beamformers, recovers user data streams transmitted by the user terminals from return downlink signals. The ground network, using beamformers generates forward uplink signals from appropriately weighted combinations of user data streams that, after relay by the end-end-end relay, produce forward downlink signals that combine to form user beams.

  • Patent number: 10244407
    Abstract: In one implementation, load balancing within a constellation of communications satellites is performed. Anticipated positions of satellites are determined. Each satellite is configured to provide multiple beams that define a coverage footprint for the satellite. Based on the anticipated positions of the satellites, it is determined that a first coverage footprint for a first satellite provides primary coverage of a high traffic region and portions of the first coverage footprint for the first satellite also will be covered by coverage footprints for other satellites, Based on these determinations, a beam assignments are defined in which a first subset of beams of the first satellite configured to provide coverage of a first portion of the first coverage footprint are inactive and a second subset of beams of the second satellite are active. The second subset of beams of the second satellite provide coverage within the first portion of the first coverage footprint.

  • Patent number: 10218068
    Abstract: Various embodiments presented herein relate to determining mutual coupling between a pair of antennas in an array antenna. Various operations presented herein enable comparison between a magnitude and phase of a signal transmitted from a first feed network (via a first antenna) and a magnitude and phase of a portion of the signal received at a second feed network (via a second antenna). Electrical effects engendered by any of the first feed network, a first switch, a first local circuit, the second feed network, a second switch, and a second local circuit can also be determined and their effects mathematically removed. Based upon the foregoing, a mutual coupling between the pair of antenna is determined.

  • Patent number: 10205498
    Abstract: An enhanced Node B (eNB) for precoding is generally described. In some embodiments, a first precoding-matrix indicator (PMI) and a second PMI is received on an uplink channel from user equipment (UE). Symbols for multiple-input multiple output (MIMO) beamforming may be precoded by the eNB using a precoder matrix recommended by the first and second PMIs, for a MIMO downlink orthogonal frequency division multiple access (OFDMA) transmission. The first PMI and the second PMI are calculated by selecting a representative codeword that is indexed by i1 and i2 for a plurality of 2TX constituent beams, the 2TX constituent beam that provides the best system evaluation metric. The i1 index for wideband and the i2 index for each subband are identified from the defined 2TX constituent beam.
