| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | A feature utilizing frequency offsets is used as a collision detection method in the wireless physical quantity conversion-summary collection (PhyC-SN) method, in which sensor information is converted into carrier waves and transmitted. The authors have improved the discriminability by suppressing inter-carrier interference using the long-interval FFT, but the accuracy is still degraded due to the similarity of frequency offsets between the transmitting terminals. Therefore, we propose a collision detection method with improved accuracy by transmitting at different frequency offsets and reducing the probability of frequency offset proximity between terminals. | |
