  • Patent number: 11438910
    Abstract: A transmitter communicates with a receiver via a satellite station that transmits a signal by a multibeam system. The transmitter includes a scheduler and a transmission unit. The scheduler performs scheduling to determine a time and a wireless channel to transmit data addressed to the receiver based on an area where the receiver is present. The transmission unit transmits a signal of the data addressed to the receiver to the satellite station by the wireless channel determined by the scheduler and at the time determined by the scheduler. The signal transmitted from the transmission unit by an i-th (i is an integer of 1 or larger) wireless channel is transmitted from the satellite station to the receiver by an i-th beam. Frequencies of signals transmitted from the satellite station by respective beams are same.

    Abstract: A digital or smart array antenna has at least one radio and a processor coupled to each antenna element. The processor is coupled with programmable logic that demodulates a plurality of signals received at one antenna element to obtain demodulation symbols. After obtaining the demodulation symbols, the programmable logic applies a weighting function. In this order or sequence, the digital array antenna is able to reduce the processing requirements associating within the signal information. The reduced processing requirements enable the signal information to be shared with adjacent antenna elements that may be timing adjusted between adjacent elements. Then, the sharing continues across all elements the array until the signal reaches an edge of the array. At the edge of the array, a signal beam may be generated that is steer in response to the processed signal information shared between all the elements in the array.

    Abstract: In a terminal position estimation system, a terminal position estimation apparatus, or a terminal position estimation method, an electric wave is received by a reception antenna of a communication terminal and is transmitted from multiple transmission antennas. A communication terminal position is estimated based on a magnetic field strength of the electric wave. When the communication terminal position is estimated, a position satisfying an approximate expression is estimated as the communication terminal position. The approximate expression shows a magnetic field strength distribution and is expressed by two variables of a distance from the multiple transmission antennas to the communication terminal and an angle between an axial direction of the multiple transmission antennas and a direction in which the communication terminal is positioned.
