Patent ID: 8050620

Claim:
A wireless station used as one of a plurality of relay stations forming transmission paths, respectively, different from each other, in a wireless transmission system for transmitting a packet from a transmitting station to a receiving station through the plurality of relay stations, the wireless station comprising: a reception section for receiving a packet transmitted from the transmitting station, and for receiving a packet which is transmitted, based on the packet transmitted from the transmitting station, from another of the plurality of relay stations, and is transmitted before the wireless station performs transmission, by using a transmission parameter for obtaining a path diversity effect in the wireless transmission system; a transmission parameter estimation section for estimating the transmission parameter used by the another relay station, based on the packet received by the reception section from the another relay station; a transmission parameter selection section for selecting a transmission parameter other than the transmission parameter used by the another relay station, the transmission parameter used by the another relay station being estimated by the transmission parameter estimation section; and a transmission section for transmitting, to the receiving station, the packet received by the reception section from the transmitting station, by using the transmission parameter selected by the transmission parameter selection section, wherein the transmission parameter selected by the transmission parameter selection section represents at least one of a delay amount for delaying a timing at which the packet transmitted from the transmission section is to be received by the receiving station, and a symbol waveform used by the transmission section for modulating the packet received from the transmitting station.
