A Streamlined Approach to DRM Receiver Design

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.

New HF SDR prototype from the makers of #AirSpy

Twitter user @lambdfew who's author of Airspy and SDR# has posted a few screenshots of new HF SDR prototype which has a -107dB noise floor and 18 bits of dynamic range.
