摘要： A space photovoltaic power generation system including a plurality of power satellites arranged in space, each of which converts electrical energy, into which sunlight has been photoelectric-converted, into a microwave, and transmits the microwave to an electric power base. The space photovoltaic power generation system divides the plurality of power satellites into a number of power satellite groups and adjusts the amount of phase adjustment to be made to a microwave which each of the plurality of power satellites included in each power satellite group will transmit so that a plurality of microwaves from the plurality of power satellites included in each power satellite group are in phase with one another. The beamwidth of the plurality of microwaves can be reduced without increasing the area of the aperture of a transmission antenna of each of the plurality of power satellites. If the plurality of microwaves transmitted from the plurality of power satellites included in each power satellite group interfere with microwaves transmitted from any other power satellite group, the beamwidth is reduced. To avoid the reduction in the beamwidth, each of the plurality of power satellites included in each power satellite group modulates the phase-adjusted microwave so as to generate an incoherent microwave so that the microwave does not interfere with other microwaves transmitted from any other power satellite group.

摘要： A space photovoltaic generation system including a plurality of power satellites arranged in space, each of which converts electrical energy, into which sunlight has been photoelectric-converted, into a microwave, and transmits the microwave to an electric power base. The system can thus transmit a microwave of high power to the electric power base. Each of the plurality of power satellites modulates the generated microwave so as to generate an incoherent microwave before transmitting it to the electric power base, thus reducing the power density of the electric power transmitted to the electric power base on the earth and hence a loss in the total amount of energy transmitted to the electrical power base on the earth.

The demodulator circuit is constructed to demodulate a received OFDM-modulated packet signal including a preamble that has two or more fixed-signal sequences, and to have a frequency-error estimating/correcting function that estimates the frequency error of the received signal by using the received preamble and corrects the received signal for the frequency error, a fast Fourier transform function (FFT portion 210) that converts the time-axis information of the corrected received signal to frequency-axis information, a transmission path response estimating/correcting function that estimates the status of the transmission path from the converted signal and corrects the received signal for the transmission path response, and an averaging function that averages the received signal after being corrected for the frequency error so that the averaging can be performed before the fast Fourier transform process.

A predrive circuit 17 drives a power circuit 11 comprising first and second power elements P1 and P2 by controlling the gate and source potential of the power elements P1 and P2 based on a stored control state. The control state is detected from a logic signal output from an input signal processor 13, which converts a command signal instructing turning on and off the power elements P1 and P2 to predetermined logic signals. Operating power is drawn from a main dc power source V1, a control power source V2, and a power supply capacitor C1 that is charged using an output voltage from the control power source V2.
