| Abstract: | The software radio is to build flexible radio systems, multiservice, multistandard, multiband, re-configurable and reprogrammable by software. A software implementation of the user terminal is able to dynamically adapt to the radio environment in which it is, time by time, located. In this article, the architecture of software radio is objectively introduced, and the technological challenges are analyzed according to its architecture and the development of related technologies. At the same time, the corresponding solutions are studied, including the application of smart antenna, DSP technology and wideband ADC in the software radio. |
