A transmission weight generation unit generates a plurality of transmission weights, while a communication quality obtain unit obtains a value indicating communication quality of each eigenpath. A transmission control unit, if reducing a size of a packet, controls to transmit the packet by dividing it into a plurality of eigenpaths and selects a transmission weight such that respective communication qualities of the eigenpaths become equivalent. The transmission control unit, if not reducing the size of the packet, controls to generate a plurality of packets and to transmit the packets by the eigenpaths and selects a transmission weight which maximizes overall communication quality of the plurality of eigenpath. A transmission weight policy determination unit obtains a type of the packet at transmission of the packet and determines whether to reduce the size of the packet.
