Abstract: PROBLEM TO BE SOLVED: To continue the communication of data between the communication terminals which are connected to the 1st and 2nd networks respectively with no influence of a variance factor of the 1st network by providing a means which displays the configuration information on a communication node of the 2nd network via a 2nd interface means. SOLUTION: A means is provided to recognize a communication node of a 1st network as a component element included in its own communication node together with a means which displays the configuration information on the component element on a communication node of a 2nd network via a 2nd interface means, etc. For instance, a request is given to a target node to which a control node 203 sends a command to show the internal configuration information on the target node before the command is sent from the node 203. Receiving the display request command, the target node, e.g. a communication node 102 displays the information on a subunit group of its own node on the node 203.

Abstract: PROBLEM TO BE SOLVED: To reduce instantaneous maximum power of a time waveform of an orthogonal frequency division multiplexed(OFDM) signal.
SOLUTION: A serial/parallel conversion section 2 provides the output of a complex information subcarrier signal to a fast inverse Fourier transform section 3, based on an information bit series. The transform section 3 applies fast inverse Fourier transform to a received subcarrier signal to obtain complex baseband time waveform with an OFDM symbol. A complex redundant subcarrier signal generating section 4 generates a complex redundant subcarrier signal for reducing the amplitude of a complex baseband time waveform of the OFDM symbol, and the transform section 3 applies fast inverse Fourier transform to the complex redundant subcarrier signal, together with the complex information subcarrier signal. Thus, the amplitude of the complex baseband time waveform of the OFDM symbol is reduced.

Abstract: PROBLEM TO BE SOLVED: To suppress the amplitude of an OFDM(orthogonal frequency division/ multiplex) time waveform, to improve transmission average power, to reduce transmission errors and to improve throughput. SOLUTION: When a retransmission request is generated, an OFDM reception part 3 gives a retransmission request signal to a scramble control part 2. The scramble control part 2 changes the scramble group of the scramble part 1 into a scramble group before retransmission. Thus, the time waveform of the OFDM symbol by a retransmission data group from a modulation part 4 changes before and after rctransmission and there is possibility that the average power of a transmission signal becomes high. Thus, possibility that transmission errors are reduced by retransmission becomes high and throughput improves.

Abstract: PROBLEM TO BE SOLVED: To suppress distortions at both ends of a transmission line frequency response, which occur through a filter. SOLUTION: The OFDM(orthogonal frequency division/multiplex) synchronous detection reception device is provided with a transmission line frequency response calculation part 4 calculating the transmission line frequency response by using the sub-carrier of an OFDM symbol which is frequency-transformed by a Fourier transformation part 3. A redundant frequency component addition part 5, adds a redundant frequency component to the calculated transmission line frequency response. The filter 7 removes a noise component contained in the transmission line frequency response to which the redundant frequency component is added.

The receiver is composed of a demodulation means 105 that demodulates a digital signal series from the synthesized frequency spectral signals.

Abstract: PROBLEM TO BE SOLVED: To provide the receiver in which the effect of reception waveform distortion due to Rayleigh fading onto a differential coding modulation signal is relaxed. SOLUTION: Amplitude outputs from signal conversion sections 4-1, 4-2 are given to amplitude ratio calculation sections 5-1, 5-2, in which a ratio of the amplitude to the amplitude received before a prescribed time is calculated. Phase outputs from the signal conversion sections 4-1, 4-2 are given to phase difference calculation sections 6-1, 6-2m in which a difference from the phase output received before a prescribed time is calculated. The amplitude ratio outputs from reception sections 3-1, 3-2 are given to an amplitude ratio synthesis section 7, where they are synthesized with a weight controlled by a weight control section 9. An output of the amplitude ratio synthesis section 7 is given to a differential amplitude shift keying(DASK) demodulation section 10, in which the result is converted into a digital data series. The phase difference outputs of the reception sections 31, 3-2 are given to a phase difference synthesis section 8, where they are synthesized with a weight calculated by the weight control section 9. An output of the phase difference synthesis section 8 is given to a differential phase shift keying(DPSK) demodulation section 11, in which the result is converted into a digital data series.
