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 transmission device transmits multiplexed signals obtained by multiplexing signals of N systems corresponding to N Orbital Angular Momentum (OAM) propagation modes. The transmission device includes: an array antenna that includes M antenna elements disposed in a lattice on a plane when viewed from the plane; and a transmitter that multiplies signals obtained by branching each of the signals of N systems into M signals by weighting coefficients of phase shift angles based on angles of the respective M antenna elements with respect to a reference axis passing through a reference point viewed from the reference point on the plane according to the OAM propagation modes, multiplexes the signals of N systems multiplied by the weighting coefficients of the phase shift angles, and transmits signals obtained by the multiplexing from the M antenna elements. M and N are integers equal to or larger than 2.
