摘要： A wireless transmitter has a modulator modulating an information signal of a frequency f1 by a carrier wave of a frequency f2 to output a first modulated signal, a transmitting antenna transmitting the first modulated signal using a linearly polarized wave, and a motor rotating the transmitting antenna at a frequency f3 to rotate the outgoing linearly polarized wave at the frequency f3 thereby multiplexing the first modulated signal with a linearly polarized wave component and a horizontally polarized wave component, the two components being independent of each other. A wireless receiver has diversity receiving antennas receiving the signal on a plurality of polarization planes to obtain a plurality of input signals; a path difference phase shifter compensating each of the input signals for the phase shift stemming from path differences, and a composer composing the corrected received signals.

摘要： It is an object to provide signal processing device and method by use of wireless communication, which is capable of analyzing status of the wireless communication in detail at a later date, compressing a wireless signal such that it can be reproduced, and reproducing the compressed signal to perform its re-reception. The signal processing device includes a reception processing unit that performs reception processing of a received signal wirelessly, a signal recording unit that records the signal, a signal compression unit that compresses an information amount of the received signal, and a signal output unit that stores the received signal that has been compressed or outputs the same to an external device. The signal compression unit divides a signal, obtained by frequency-transforming the wireless received signal, into a signal portion large in amplitude value and a non-signal portion small in amplitude value on a frequency spectrum, calculates a representative value based on a feature quantity of the non-signal portion and combines the signal portion and the representative value into a compressed signal.

摘要： When supplying a power from a base station to a terminal station on radio and a distance from a base station to a terminal station is long, it becomes impossible for the terminal station to rectify the power. The feature of the present invention is found in a wireless communication system in which the peak value and duty ratio of a transmission power are controlled simultaneously, keeping the transmission power of a base station below a fixed value, thereby allowing a voltage to be applied to a diode, which is a component of a rectifier circuit possessed by a terminal station, always in excess of a threshold voltage of the diode, and energy is exchanged between the base station and the terminal station below a limit power.

摘要： Provided is a capacitor coupling type power transmission circuit in which a variation in receiving side voltage due to a variation in capacitance is suppressed to prevent an influence on a variation in load current in a display panel. An insulating board of the display panel is sandwiched by capacitive coupling electrodes formed on each of a transmitting side board and a board of the display panel, thereby forming capacitors. A non-contact transmission is performed by the capacitors. An alternating current voltage signal obtained by electrodes on a display panel side is rectified by a rectifier including diodes. A constant voltage circuit which is a shunt regulator including a diode array in which a resistor and a plurality of diodes are connected in series is provided to maintain a stabilized voltage irrespective of a variation in load in the display panel.
