Abstract (in Japanese) (See Japanese page) 
(in English) Systems with location-aware technique have been attracted recently. Not all of them need to know the location of receivers precisely. This paper proposes a simple positioning method for small devices based on Direct-Sequence Spread Spectrum (DS/SS) signals only to identify a region where the device exists. To develop a small receiver, we employ Low Frequency (LF) signals and magneticfields as communication medium. The proposed scheme measures the sign of inner product between reference signals from a loop antenna and the delayed signal from double loop antenna. Here, the antennas have a common axis. With the antenna coordination, it can identify the region where the receiver exists based on the inner product. Numerical results show that the inner product can be useful to detect the region where the receiver belongs.
