| Abstract | ||
| In this paper, the development of multi-modulation and demodulation baseband modulator and demodulator based on Software Defined Radio (SDR) are presented. The fundamentals of digital linear modulations are presented as algorithms to develop symbol of SDR signal. The multi-modulation baseband modulator (MMBM) and demodulator (MMBD) are designed using digital signal processing (DSP) algorithms, and then implemented into Xilinx Virtex-4 FPGA. Comparing the real-time and simulation results shows that the timings are equivalent, and the sign and magnitude changes are significant. Furthermore, at least 17% FPGA utilizations have been achieved for the configurable MMBM and MMBD | ||
