Our research is aimed at the creation of various new communication systems originating from innovative concepts that open a new vista towards future generation wireless communications. Signals used in such systems must be chosen for the optimal transmission of given message data or packets, and protocol must be defined so that messages are efficiently exchanged through an array of wireless links provided by best network architecture. Decentralized wireless networks, in which no control station or base station exists, are considered to be the main target of such network topology.
