IR-UWB cognitive radio system based on the M-OAM modulations


Communication systems plays decisive role in the evolution of the transport field, and during the last years, requests to have the safest and most efficient transport modes has been expressed by users. The use of the ultra-wideband (UWB) technique can satisfy such a need. UWB offers numerous advantages such as: the large offered bandwidth, the signal flexibility, the quality of service, the transmission power and the limited cost. In this paper, a new system dedicated to the domain of transport, based on UWB technology is presented. The implementation of the new modulation M-OAM (Orthogonal Amplitude Modulation) which is based on the use of original mathematical tools called Modified Gegenbauer functions (MGF), derived from orthogonal polynomials, increases the data rate flow and enhances the robustness ensured by UWB communication for multimedia and transport applications. With the purpose of improving the functioning of the communication system and ensuring the very high data rate, this work consists in combination of UWB and cognitive radio technologies in order to develop an adapted and efficient universal receiver. This receiver is able to detect the signal arrival and identify the coding parameters used in the transmission so as to be adapted to them automatically. The receiver requires intelligent capacities of observation, learning and decision, therefore, our conception is based on the concept of the cognitive radio which is characterized with the ability to detect the presence of the signal. In this paper, we present the principle of the modulation M-OAM, the waveforms used in our system, and the method which allows the receiver to identify the type of the used modulation.
