  • Publication number: 20200279381
    Abstract: In order to track a mobile body in an efficient manner, a server collects passage trail information relating to a mobile body to be tracked from a camera provided in an information-centric network to thereby track the mobile body. Specifically, the server transmits a request message which designates a search area and a search period to the information-centric network, requesting the information-centric network to provide passage trail information relating to the mobile body, the passage trail information being acquired by the camera; receives a response message including the passage trail information; and collects the passage trail information associated with the search area and the search period designated by the request message to thereby generate tracking information.

  • Publication number: 20200092882
    Abstract: Channel interference is suppressed, and an increase in the cost of manufacturing a terminal or in maximum transmission power is adaptively suppressed. A base station retains information relating to at least one already-allocated bandwidth, among all bandwidths that are to be used for wireless communication, in a memory and determines whether the already-allocated bandwidth that is the same as a bandwidth which satisfies terminal performance information, according to a request for communication from a terminal, which includes the terminal performance information is present or absent. In a case where the already-allocated bandwidth that is the same as the bandwidth which satisfies the terminal performance information is absent, the base station determines whether a non-allocated bandwidth that is the same as the bandwidth which satisfies the terminal performance information is present or absent.

  • Publication number: 20200050627
    Abstract: In order to enable a user to acquire a desired content more quickly by performing a matching process by using search target ID information identifying a search target so as to properly acquire a content regarding the search target and to shorten a time required to complete the matching process, a communication device such as router is configured such that, when receiving an interest form a content-centric network, the communication device performs a search process on contents accumulated therein, aiming to find one or more contents which meet a search criteria set specified by the interest, performs the matching process for verifying whether the content found in the search process matches the search target ID information (face image) to acquire a content regarding the search target, and transmits the acquired content to a communication device of a content request source.

  • Publication number: 20190238266
    Abstract: A base station transmits an OFDM signal to a mobile station, using carrier frequencies of a frequency band shared with another system. The base station includes a frequency selector that selects an unused frequency band based on an interference level of the frequency band, selects a carrier frequency for systematic-bit mapping, and selects a carrier frequency for parity-bit mapping, and a turbo coder that performs turbo coding processing on transmission data and outputs a systematic bit and a parity bit. The base station also includes a carrier-mapper that performs systematic-bit mapping and parity-bit mapping, and a control-signal generator that generates a control signal containing band-division-count information and signal-type information. The base station further includes an orthogonal frequency division multiplexer that generates the OFDM signal and a transmitter that transmits the OFDM signal to the mobile station.

  • Patent number: 10305630
    Abstract: An object is to suppress a decrease in communication quality and improve the communication quality even when interference is present in some of a frequency band in use in a case where a turbo coding scheme is combined with multicarrier communication using some of a frequency band shared with another system. A frequency selector (107) selects a band not used by another system, based on a measurement value of a reception level, then selects a subband for systematic-bit mapping from among subbands having a measurement value of the reception level lower than a threshold, and selects a subband for parity-bit mapping from among subbands other than the subband for systematic-bit mapping, for each subband (carrier frequency) of the selected band. A carrier-mapper (110) maps a systematic bit and parity bit to each subband based on the result of selection by the frequency selector (107).

  • Patent number: 8279953
    Abstract: A transmitting apparatus, a receiving apparatus and a wireless communication method for suppressing interference between codes, while further reducing the ratio of redundant components occupying a signal to improve the transmission efficiency. The transmitting apparatus (100) transmits a signal having a frame structure in which a plurality of symbols follow a pilot symbol to which a guard interval has been added. In the receiving apparatus (200) that receives that signal, a long FFT target section acquiring part (202) acquires, from the received OFDM signal, a long FFT target section that is a target section in which delay waves are to be removed by use of a pilot symbol. A long FFT part (203) performs a fast Fourier transformation of the long FFT target section to convert it to a frequency domain signal. A frequency equalizing part (204) performs a frequency equalization of the long FFT target section by use of an interpolation result of communication line estimation value.

  • Patent number: 8121213
    Abstract: A modulation apparatus is disclosed that enables significant improvements in signal transmission rate in a limited frequency band as compared with conventional modulation schemes. The modulation apparatus has first and second frequency-increasing single side band (SSB) modulators. The modulators are configured to have respective carrier frequencies with a difference by a frequency corresponding to the symbol frequency (i.e. fundamental frequency of the input symbol). An adder combines a lower side band (LSB) signal obtained from the SSB modulator set for a higher carrier frequency, and an upper side band (USB) signal obtained from the SSB modulator set for a lower carrier frequency to obtain a modulation signal.

  • Patent number: 7995663
    Abstract: To narrow the dynamic range of multicarrier signals and prevent both the increment of cost and the degradation of power efficiency. A modulating part (101) modulates transport data. An S/P converting part (102) performs an S/P conversion of a modulated symbol and outputs the modulated symbols, the number of which is the same as the number of all subcarriers, to an IFFT part (103) in parallel. The IFFT part (103) assigns the modulated symbols to the subcarriers, the frequencies of which are orthogonal to each other, to perform an inverse fast Fourier transform. A P/S converting part (104) performs a P/S conversion of the signals of time domain. When the instantaneous amplitude level of an OFDM signal is lower than a predetermined threshold value, a pit clip part (105) replaces this amplitude level by the predetermined threshold value.

  • Patent number: 7936811
    Abstract: A modulating device capable of generating an OFDM signal and having a drastically improved frequency use efficiency. The modulating device has modulators (6, 8 (11, 13, 106, 108, 111, 113)) for modulating a signal to be modulated and having a Nyquist roll-off frequency characteristic with a carrier frequency having a difference two times the Nyquist frequency and combiners (10(15, 110, 115)) for generating modulation output having a speed two times that of the signal to demodulated and the same Nyquist roll-off slope as the signal to be modulated by combining the outputs of the modulators (6, 8 (11, 13, 106, 108, 111, 113)). Thus a double speed wave can be superposed on the same frequency without varying the roll-off slope of the Nyquist characteristic, and therefore an OFDM signal (19) having a drastically improved frequency use efficiency is provided.
