The goal of this article is to define the Technology of the Software Defined Radio (SDR), also the Digital Signal Processor (DSP) and the commercial applications of those devices for that new technology of RF communications. It is considered here a brief description of the SDR Technology, the model of communications across conventional system totally implemented by hardware (HDR) comparing to the SDR Technology. We also mention the RF signal treatment RF by the SDR ideal architecture and the challenges to be get over in the next years.
