【Abstract】 Because of its flexibility, software radio use is expanding and evolving. And the technology has become an important research and development topic. In this paper, the system configuration of Software Radio is discussed and some Digital Signal Processing methods are introduced. Fundamental elements of DSP including bandpass sampling theory and multirate digital signal processing (MRDSP) and a widely used kind of highly effective filter are briefly introduced. And some information of AD6640 is included in this article.更多还原
