Abstract

The invention relates to distributed wireless ad hoc networks having interfering transmission channels, in which direct links between adjacent transmit nodes and receive nodes in a connection pair are established and optimized. The inventive signaling method alternately uses a primary network and an adjoint network, the respective transmit nodes and receive nodes constantly changing their roles in an agreed time pattern. The transmission signals in the adjoint network are predistorted in such a way that the influence of the proper mobile radio channel is canceled on each transmission channel. The occurring interference is implicitly transmitted as well by the receive nodes and can be directly determined and taken into account by the transmit nodes.
