This paper presents the implementation of an Impulse Radio Ultra Wide Band (IR-UWB) communication system based on Orthogonal Amplitude Modulation (OAM) on the FPGA board (Field Programmable Gate Array). The Orthogonal Amplitude Modulation is a new modulation technique that provides a high data rate transmission, using the orthogonal waveforms named MGF (ModifiedGegenbaeur Function). In this work, the FPGA card and the converters DAC(Digital-to-Analog Converter) and ADC (Analog to Digital Converter) are considered to perform the implementation. The system is running in the simulation field and in the real system on the hardware equipment.The obtained results show that the implementation of UWB-OAM system on FPGA board is running well andprovide a high -real time computations system.

“…One main difficulty for choosing the appropriate waveform is to have, simultaneously, a good BER performance and a high data rate [1] [4]; in order to have these performances, different orders of Hermite and Gegenbauer polynomials [12][13] [14], which are defined respectively by equations 2 and 3 and represented respectively in figures 2 and 3 had been studied:…”

Intelligent transport system (ITS) exploits new communication and information technologies to make existing infrastructures more effective and more reliable, it resets on functions associated with the intelligence. The use of the ultrawideband (UWB) appears as a very suitable technology for this kind of applications, due to its large bandwidth, its resistance to the interferences with other radio systems and also the quality of the offered service. In this paper, a new system dedicated to the domain of transport [5], 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 and enhances the robustness ensured by UWB communication for multimedia and transport applications.With the purpose of improving the performance of the communication system and ensuring the autonomy for our system, this work consists to combine the UWB and cognitive radio technologies in order to develop an adapted and efficient 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 spectrum sensing for cognitive radio which is characterized by the ability to detect the presence of the signal.

“…The amplitude of the pulse should be normalised to comply with Federal Communications Commission mask. The wide bandwidth issued (several GHz) allows signals with a precise temporal resolution, low probability of interception/detection and offers robustness against multipath fading [3]. Thus, the UWB radar offers a great interest in short‐range road safety applications [4].…”
