  • Patent number: 9154358
    Abstract: A wireless communication device according to the present invention includes a standard signal holding unit for holding standard signals, a correlation value calculation unit for performing a correlation operation between a received signal and the standard signals, and a reference signal selection unit for determining a reference signal from among the standard signals on the basis of a correlation operation result obtained by the correlation value calculation unit. When a correlation value peak which provides a maximum value is not detected among a correlation values obtained by the correlation operation between the received signal and the standard signals, the reference signal selection unit repeats a predetermined number of times, a process of performing a correlation operation between a new standard signal which is generated so that a head of a data part is located at some midpoint in a predetermined symbol interval and the received signal.

  • Patent number: 8781518
    Abstract: A communication device and method are disclosed. Transmitted signals are transmitted from antennas. A beam is formed based on known-received signals by controlling a transmission directionality of the antennas. Transmitted power of the transmitted signals is controlled based on a time interval between a reception time during which the known-received signals are received and a transmission time during which the transmitted signals are transmitted.

  • Publication number: 20140093020
    Abstract: A wireless communication device according to the present invention includes a standard signal holding unit for holding a plurality of standard signals, a correlation value calculation unit for performing a correlation operation between a received signal and the plurality of standard signals, and a reference signal selection unit for determining a reference signal from among the plurality of standard signals on the basis of a correlation operation result obtained by the correlation value calculation unit. When a correlation value peak which provides a maximum value is not detected among a plurality of correlation values obtained by the correlation operation between the received signal and the plurality of standard signals, the reference signal selection unit repeats a predetermined number of times, a process of performing a correlation operation between a new standard signal which is generated so that a head of a data part is located at some midpoint in a predetermined symbol interval and the received signal.

  • Publication number: 20120020281
    Abstract: An EVM measurement unit measures the EVM of received signals, and performs a weighted average on them so as to derive MSE. A frequency acquiring unit acquires the change frequency of modulation scheme and the occurrence frequency of data retransmission. A moving status acquiring unit acquires the variation situation in moving velocity of a terminal apparatus or positional relationship between a base station apparatus and the terminal apparatus. A threshold modifying unit determines the modulation scheme used for the next communication, based on the value of MSE and other pieces of information described above.

  • Publication number: 20110002312
    Abstract: A radio controller, which prescribes repetition of a frame formed by a plurality of downlink time slots and a plurality of uplink time slots, and which allocates a first data to be broadcast and a second data to be transmitted to a personal station with switching to the downlink time slots corresponding to each other in each frame. Further, the radio controller allocates a third data, which should be received from the personal station, to the uplink time slot corresponding to the downlink time slot allocated to the first data and to the uplink time slot corresponding to the downlink time slot allocated to the second data. A RF unit, a baseband processor, and a modulator/demodulator transmit the allocated first and second data. Further, the RF unit, the baseband processor, and the modulator/demodulator receive the allocated third data.

  • Patent number: 7280680
    Abstract: In order to make observation of localizations of in vivo expressed genes possible in an entire individual living organism such as animals, and plants, a living genetic recombinant specimen containing a marker that can be detected at the time when specific genes are expressed is sequentially severed, sectional images each of which corresponds to an image of sections severed are photographed in every scissions of the living specimen, and three-dimensional observation of the living specimen is implemented on the basis of the images photographed in every scissions described above, whereby three-dimensional localizations of expressed genes are observed in the living specimen.
