Patent ID: 7664093

Claim:
A wireless station for use in a wireless transmission system, the wireless transmission system having a plurality of wireless stations able to transmit packets, and having a path diversity system formed by a transmitter-side wireless station, a multi-path channel, and a receiver-side wireless station, the wireless station comprising: a delay amount determining section for randomly selecting a delay amount from among a plurality of candidate values as a delay amount for which to delay a packet transmission; a transmission timing control section for determining a transmission start timing to start the packet transmission, the transmission start timing being obtained by delaying a reference timing by the delay amount selected by the delay amount determining section, the reference timing being a reference for the packet transmission; and a transmitting section for transmitting the packet at the transmission start timing determined by the transmission timing control section, wherein a difference between any two candidate values of the plurality of candidate values is greater than or equal to a predetermined delay resolution, and a difference between a maximum candidate value of the plurality of candidate values and a minimum candidate value of the plurality of candidate values is less than or equal to a predetermined maximum delay, and wherein the predetermined delay resolution and the predetermined maximum delay are set to values such that a plurality of delayed waves can be received with path diversity.
