Abstract:The design of programmable multi-mode digital modulator for software defined radio (SDR) technology using FPGA is developed and investigated in this paper. The system generator from Xilinx and MATLAB tools are used for FPGA design as well as the implementation of the modulator over a Virtex-4 FPGA board. The HDL language on Xilinx ISE is used to generate the bit stream of the modulator algorithms into ADC/DAC device and FPGA board. The modulated signal obtained from MATLAB simulation is evaluated with the test… Show more
