| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Synchronized spread spectrum code division multiple access (SS-CDMA) is very effective for increasing the capacity and reducing the interference with a rapid spread of Internet of things (IoT) devices. Since the synchronized SS-CDMA requires to receive timing synchronization, it is essential to realize space-time synchronization. The wireless two-way interferometry (Wi-Wi) is used for precise time synchronization between nodes. In this paper, we evaluate error of initial timing synchronization (offset) of the Wi-Wi module in several conditions. Since the standard deviation of offset was less than 30 ns in all of the measured conditions, it was shown that Wi-Wi is capable of high-precision initial timing synchronization. | |
