Software defined radio turns digital radio reception into an application
ALEXANDER ZINK AND MARTIN SPEITEL
Software Defined Radio (SDR) turns the hardwired, task-specific and very elaborate chip development of the past into a flexible software-based design running on a generic, efficient and mass-produced hardware platform. It is not a new concept, but it is becoming a reality in more and more technical systems. Digital radio receivers are one major example for SDR technology, because modern processor platforms offer enough computing power to build almost the complete radio functionality in software.
