Abstract
A wireless transmission system is provided in a place where two or more wireless networks uncoordinated to each other are located and are subjected to receive mutual interference. This system can transmit data correctly with no limitation of the use of communication apparatus even if the transmission is subjected to the interference from the other network. Namely in an ultra wide band wireless transmission system, orders of the slots of a frame are replaced randomly by a predetermined slot permutation pattern, and then the replaced slots are transmitted. The orders of received slots are restored to the original order by the predetermined slot permutation pattern. Thereby, a diversity effect to interference can be obtained. Consequently, even if two or more networks uncoordinated to each other, in which the ultra wide band wireless transmission system operates, are located closely, communication in each network can be performed correctly.
