| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In wireless sensor networks, a few devices, out of a large-enough possible devices equipped with a common code, wants to simultaneously communicate to an access point (AP). From the received superimposed signals, AP recovers messages after a modulo 2 operation to a pre-processed signal, and remove the estimated ones from the signal. AP repeats this processing until the average power of the signal is lower than a threshold. Simulations show that AP recovers all the messages from active devices, even when some of messages are the same, i.e. collided. | |
