摘要： Provided is a wireless relay system that improves system throughput between terminal stations and flexibly makes system throughput variable with respect to short-term traffic fluctuations. In the wireless relay system, a plurality of relay stations relay communication between two terminal stations that perform random access. The terminal stations and the relay stations include a slot synchronization unit, a time synchronization unit, and a transmission unit. The slot synchronization unit synchronizes slot timing of a time slot indicating a unit time. The time synchronization unit performs time synchronization for synchronization of the slot timing. The transmission unit transmits a transmission packet to a wireless line in synchronization with the slot timing. A transmission right is allocated for at least one time slot to each of a plurality of groups which are configured so that a group of a terminal station or a relay station and a group of an adjacent terminal station or an adjacent relay station are different from each other. The transmission unit transmits the transmission packet to the wireless line only in a time slot in which the transmission right is allocated to the group to which the terminal station or the relay station belongs.

摘要： It is possible to reduce the effect of an interference signal while suppressing increases in a circuit scale and a processing time. A reception device receives a multicarrier signal and an interference signal via a radio transmission path, detects a frequency position of the interference signal, performs filtering to suppress the multicarrier signal and the interference signal at the detected frequency position of the interference signal, removes a guard interval from the multicarrier signal suppressed by the filtering, demodulates each subcarrier of the multicarrier signal from which the guard interval is removed, and performs error correction on the demodulated signal.
