Phần mềm xác định radio P11

The subject of software radio emerged as a ‘hot topic’ in mobile communications in the early 1990s, when many people saw the technology as a solution to the problems of complex RF and IF processing required in modern multimode/multiband mobile terminals. Today, software radio is seen more as a technology to enable the reconfiguration of terminals by download. 1 Such reconfiguration can be achieved at all stages from design, through production, to post purchase use by the consumer.
