摘要： A beacon slot position control section (205) of a radio communication apparatus constituting a radio network system which detects whether empty beacon slots are present in a beacon period. When an empty beacon slot is present before the period in which the radio communication apparatus transmits a beacon, a movable counter (206) starts counting a specified number of super frames. When the count is completed, the radio communication apparatus transmits a beacon of the radio communication apparatus at the earlier empty beacon slot. Consequently, since the empty beacon slots are eliminated and the beacon period is compacted, even if the number of radio communication apparatuses joining the radio network system fluctuates dynamically, the radio communication apparatus can perform radio communication with high efficiency and less waste of consumed electricity.

摘要： A radio communication device includes a beacon reception unit extracting a frame from a received beacon and a frame judgment unit judging whether the extracted frame is one requiring data transmission/reception or one giving notice of a collision with a beacon of another network, a frame constructing unit used when the frame judgment unit has judged that the frame is a collision notification, generating a frame for relaying the collision notification and a movement notification to a new beacon transmission period, and a beacon transmission instruction unit instructing transmission of the frame at the beacon transmission timing. Accordingly, since these notifications can be relayed, all radio communication devices of the same network can move to a new beacon transmission period while avoiding a collision with a beacon from a radio communication device of another network.

摘要： Using an inputted transmission information signal, a synchronizing signal and a data signal are generated. The synchronizing signal is set at and outputted to a first frequency channel comprising at least one frequency channel. The data signal is set at a second frequency channel comprising at least one frequency channel. The first frequency channel and the second frequency channel use frequency channels different from each other. This provides the signal synchronizing information at a frequency channel separate from that of the data. A sufficient time can be assigned for synchronization, making it possible to swiftly demodulate the signal during data reception.

摘要： A communication system includes a modulating circuit to increase the amount of information to be transmitted, a transmitting apparatus capable of easily generating a desired waveform even for any very short wavelets, a receiving apparatus capable of easily separating wavelets even if the intervals thereof are narrow. The modulating circuit includes clock generating, transmission signal generating, control signal generating, delay and wavelet generating parts. The clock generating part generates a clock signal at predetermined time interval “Tp”. The transmission signal generating part generates a transmission signal at interval “Tp”. The control signal generating part outputs a control signal of a predetermined duration based on the clock signal. The delay part generates the control signal as a delay signal that has been delayed by a delay amount based on the transmission signal. The wavelet generating part generates a wavelet at the generation timing of the delay signal.

摘要： A fingerprint identification system comprising: an IC card having a tamper-resistance; and a reader/writer having a tamper-resistance for reading/writing information from/into the IC card. In the reader/writer, a fingerprint image, as read by a fingerprint input unit, is preprocessed in a preprocessing unit, and extracted intermediate information is transmitted to the IC card. This IC card compares the intermediate information with the fingerprint information, and makes authentication information usable for an electronic authentication upon matching. By this electronic authentication with applications, the fingerprint identification system, which has a high level of safety and can reduce the cost is provided.

摘要： An A/D converter converts the signal received by an array antenna and frequency-converted to a digital signal by a frequency converter. A correlation detector uses the chip rate as a cycle frequency and calculates a cyclic correlation matrix of spread spectrum signals stored in data storage. A cycle frequency detector detects the cycle frequency of an interference signal output from A/D converter. A correlation detector uses the detection result of the cycle frequency detector as a cycle frequency and calculates a cyclic correlation matrix of the signal, which becomes an interference signal, using the signal output from A/D converter. A direction of arrival is estimated, using the cyclic correlation matrices calculated by correlation detector and the correlation detector calculates the respective eigenvalues and eigenvectors and estimates the directions of arrival of a spread spectrum signal and a signal, which becomes an interference signal.
