There’s a problem with software defined radio. It’s not that everyone needs to re-learn what TEMPEST shielding is, and it’s not that Bluetooth is horribly broken. SDR’s biggest problem is one of ...

Making a software defined radio (SDR) receiver is a relatively straightforward process, given the right radio front end electronics and analogue-to-digital converters. Two separate data streams are ...

No doubt most tech and electronic enthusiasts have encountered buzz around SDR, software-defined radio, and asked themselves “what’s the sudden big deal,” if the technology existed for decades? The re ...

The article makes the case for software defined radio (SDR), and discusses strategies for balancing flexibility, energy efficiency and spectrum use. It looks at different hardware architectures, ...

After a prolonged and costly gestation, software-defined radio (SDR) technology is gaining ground. Airborne tactical networking radios, data links and relays based on SDR architectures are being ...
