| Abstract: | Software Radio and Direct Digital Frequency Synthesis are two novel techniques, because of their advantages, they have be- come two hotspots and widely applied in modern communication field. The common concepts, fundamentals and characteristics of the technology of Software Radio and Direct Digital Frequency Synthesis are illustrated in this paper. Three applications of Direct Digital Frequency Synthesis Technology in the Software Radio are introduced, and a primary implemental scheme of multiple modulation sig- nal generator based on Software Radio using DSP DDS structure is offered. |
