ABSTRACT
This Project is the part of a big project that has been developed by research group Communications Numériques (COMNUM) in the Departement of Opto-Acousto-Electronique (DOAE) at the Institut d'Electronique de Microélectronique et de Nanotechnologie (IEMN) Valenciennes, France. The project concerns is the development of high mobility communication with low power energy consumption. This paper proposes the utilization of UWB (Ultra Wide Band) as the basic signal pulse for telecommunication. It will be generated with new technique of modulation OAM (Orthogonal Amplitude Modulation). The potential advantages of UWB transmissions such as low power, high rate, immunity to multipath propagation, less complex transceiver hardware, and low interference, will be combined with the superiority of FPGA (Field Programmable Gate Array) which provides high speed, high level of integration, high flexibility, and low development costs. The system will be running in the simulation field and in the real system on the hardware equipment. The FPGA card is ADM-XRC-5T1 based on Xilinx Virtex 5, merged with DAC (Digital to Analog Converter) card XRM-DAC-D4/1G. We will see that implementation of UWB with modulation OAM on FPGA will be running well in simulation, but for implementation in real system we should make several adaptation and experiment. No wonder that the real system implementation in FPGA are much more complicated and different with the simulation base on software.

This thesis discusses about the implementation of an Ultra Wide Band (UWB) communication system based on the FPGA (Field Programmable Gate Array) using the Orthogonal Amplitude Modulation (OAM) which is the newer modulation technique that can provide a higher speed of data transmission rate. The OAM (Orthogonal Amplitude Modulation) is the combination between the Bi-Phase Modulation (BPM) and Pulse Position Modulation (PPM) using the orthogonal signal. The work is focus on the ADC data captured, performing parallel correlation, synchronization and decoding process. The basic principle of the system is: the transmitted signal is first coded into the symbols by using 4- OAM. Then, this data are transmitted by a UWB antenna. The UWB antenna on the receiver side receives these signals and captured by a high speed ADC and results 16 data samples in parallel on every FPGA clock cycle. These signal are performed the parallel correlation with the reference signal which is stored in the FPGA memory. The results of correlation then can be decoded by firstly finding the peak of correlation result which is refers to the received symbol. By using the PCI express communication, the decoded data is transferred to the host application as a valid data received.
