摘要： A quadrature demodulator includes a reception section which receives a signal transmitted by an RFID tag and containing a specific pattern and data following the specific pattern and multiplies the reception signal by a local signal to generate an I-signal, while multiplying the reception signal by the local signal shifted in phase by 90 degrees to generate a Q-signal, a first demodulating circuit which squares the I- and Q-signals and adding the resulting I- and Q-signals together to generate data on the basis of the addition result, a second demodulating circuit which detects the specific pattern in the I- and Q-signals to decode the data following one of the detected specific patterns, and a control section which selects one of the first and second demodulating circuits in accordance with a gain determined by the result of the addition between the values of the squared I- and Q-signals.

摘要： A radio communication apparatus sends a signal for assigning a predetermined number of slots to one or more response devices. The response devices individually select one slot, and transmit own specific identification information in that slot. The radio communication apparatus has an all slot number counter and an empty slot number counter. The all slot number counter counts the number of all slots received within a slot counting period. The empty slot number counter counts empty slots among those received within the slot counting period. The radio communication apparatus calculates an estimated number of unread response devices whose identification information is not yet read, from the counted values of each counter and the number of slots at the present time. And, based on the estimated number of unread response devices, the radio communication apparatus determines the number of slots to be assigned next.

摘要： An RF tag reading apparatus reads information from RF tags affixed to postal envelopes by a single operation. An article container contains a large number of postal envelopes provided with RF tags. A reader antenna, which is connected to an interrogator via a coaxial cable, is disposed under the article container. Maximum gain directions of the RF tags of the respective postal envelopes are uniformly directed to the reader antenna. The respective postal envelopes contained in the article container are arranged face to face with each other in a direction orthogonal to the maximum directions of the RF tags. Since a maximum gain direction of the reader antenna is oriented toward a base end surface of the article container, the maximum gain directions of the RF tags are opposed to the maximum gain direction of the reader antenna.

摘要： A hopping pattern setting section sets, as a frequency hopping pattern code, elements of a matrix in which all integers of “1” to “the number of frequencies to be used” appear only once and which is obtained by adding, as an offset, any one of integers of “0” to “(the number of frequencies to be used)−1” to each of elements of a matrix obtained by excluding integers larger than the number of frequencies to be used from a matrix in which all integers of “1” to “(prime number larger than the number of frequencies to be used)−1” appear only once. A frequency oscillation section converts the frequency hopping pattern code into the frequencies to be used to output unmodulated signals of the frequencies to a transmission section and a reception section.
