Design and FPGA real-time implementation of PWM and PPM modulation for Ultra Wide Band applications

Because of its high power efficiency, transmission efficiency and strong anti-jamming capability, PPM is widely used in spite the difficulty of synchronization between transmitter and receiver at the beginning of each symbol. The simplicity and the capacity of ultra wide Band initiate a lot of research activities from both academia and industry applications especially in wireless communication field. This paper discuss the FPGA implementation of PWM and PPM for Ultra Wide Band communications. The proposed design was simulated using Xilinx Vivado software tool and targeted on Nexys 4-DDR Board with Artix-7 FPGA device. Data input was generated using both DDS Compiler and Analog Discovery 2 with Pmod AD5 Analog to Digital Converter. Experimental results present a good compromise between low FPGA resources, low power consumption and high speed. These results demonstrate that our approach is competitive to other related works and can be widely used in many Ultra Wide Band (UWB) applications.
