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： Corresponding to transmission data 101, phase controller 105 is controlled to shift a phase of modulated signal 103 by 0° or 180°. Planes of polarization of modulated signals to be transmitted from antennas 106 and 107 are made different from each other corresponding to transmission data 101. The electric field strength of a signal received at antenna 108 changes corresponding to the plane of polarization, thereby voltage value 113 output from electric field strength detector 111 varies corresponding to transmission data 101, and using this variation, judged result 115 is obtained. Two results, namely, demodulated data 112 and judged result 115 are input to comparing circuit 116, whereby the reception apparatus is capable of obtaining received data 117 with high quality.

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.

摘要： A radio terminal device has an antenna element, a coil, a switch, an RF circuit section and a conductive substrate. The switch is used to switch between a case where current distribution exists only in the antenna element and its vicinities and a case where the current distribution exists not only in the antenna element and its vicinities but also in other places. Additionally, the switch is switched in accordance with the usage pattern in which the user uses the radio terminal device (e.g., telephone call and data communication). This allows the transmission/reception to be performed with the antenna polarization and directivity suitable for the usage pattern. Thus, there can be provided a radio terminal device that exhibits a reception characteristic suitable for a respective situation.
