摘要： PROBLEM TO BE SOLVED: To provide a diversity receiver, wherein a gain is improved more than a receiver employing a single antenna, a similar array gain to a receiver according to equal gain combination or maximum ratio combination can be obtained, and mounting is facilitated approximately equally to a receiver according to selective combination. SOLUTION: A diversity receiver 10 comprises: a changeover switch 11 for switching output destinations of signals; a first adder 12 for adding two signals; a π phase shifter 13 which outputs an input signal while having a phase difference of 180°; a second adder 14 for adding two signals; an RSSI measuring circuit 15 for measuring a received signal strength; a control circuit 16 for controlling a switching operation of the changeover switch 11; and a receiving circuit 17 for receiving signals. The control circuit 16 is configured to control the switching operation of the changeover switch 11 on the basis of a control signal from the RSSI measuring circuit 15. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To avoid interference of response signals transmitted from a plurality of radio frequency tags and to improve distance measuring precision in a radio frequency tag distance measuring system. SOLUTION: A radio frequency tag distance measuring device 10 generates PN signals changing values in response to inherent assignment PN codes of the radio frequency tag of a distance measuring object, and further generates sine wave PN signals multiplying reference sine wave signals to the PN signals, and transmits a diffusion pulse modulation signal converting the sine wave PN signal into a radio signal. The radio frequency tag distance measuring device 10 receives a compression pulse modulation signal executing time compression processing to the diffusion pulse modulation signal with the radio frequency tag. The radio frequency tag distance measuring device 10 calculates a distance up to the radio frequency tag based on a phase difference between the reference sine wave signal being an origin generating the sine wave PN signal and the reference sine wave signal included in a received compression pulse modulation signal.

摘要： PROBLEM TO BE SOLVED: To facilitate a prior processing for measuring a distance in a distance measuring device for a radio tag. SOLUTION: This distance measuring device 10 for a radio tag transmits a pulse modulation signal to which diffusion processing is not applied. Each radio tag receives the pulse modulation signal transmitted from the distance measuring device 10 for a radio tag, applies the diffusion processing to the pulse modulation signal by a PN code assigned uniquely to itself, and transmits the signal to which the diffusion processing is applied as a diffused pulse modulation signal. The distance measuring device 10 for a radio tag detects a unique assigned PN code of each radio tag based on the diffused pulse modulation signal transmitted from each radio tag. The distance measuring device 10 for a radio tag measures a distance to the radio tag by using the PN code stored in a measuring object PN code storage part 20. COPYRIGHT: (C)2010,JPO&INPIT
