A few months ago, we saw a hack where a $20 USB TV tuner was transformed into a software-defined radio capable of reading GPS signals, listening to radio transmissions between aircraft and a control ...
If you’re just getting into software-defined radio (SDR) but you find some of the math and/or terminology a bit of hurdle, you could absolutely do worse than to check out these SDR tutorials by ...
Tutorial: SDR meets MIMO or, all you need to know about designing MIMO with a software-defined radio
Multiple Input, Multiple Output wireless technologies [1, 2, 3, 4, 5] are getting a lot of attention these days. MIMO has the ability to significantly increase raw ...
Old radio standards rarely die, yet new standards come on line every few years. This forces radio designers to design their systems to be compatible with as many standards as possible. Many ...
As the world becomes more interconnected and digital, software-defined radios (SDRs) become an essential part of our daily lives, with applications ranging from satellite communications and radar ...
Two years ago, I wrote about using an inexpensive RTL2832-based DVB/DAB USB dongle as a spectrum analyzer and receiver. (See “Software-Defined Radios Help Explore RF Spectrum,” July 11, 2012). It is ...
When the first USB DTV receivers came out with tuners covering 54–806 MHz, I wondered if any of them could be modified into an inexpensive spectrum analyzer. Thanks to RealTek and some Linux kernel ...
