Software defined radio or SDR is the most exciting frontier in the field of radio, transferring as it does all signal functions from the analogue to the digital domain. Radios using SDR techniques can ...

The following is excerpted from Chapter 18: Software Defined Radio from the Book, RF & Wireless Technologies by Bruce Fette. If you order a copy of this book before December 31, 2007 you can receive ...

Just recently I was shopping for a new communications receiver for ham radio and general shortwave listening. Lots of transceivers are available, but I only needed a receiver since I use a home-built ...

Like almost everything else in electronics, radios are becoming processors with software that communicate via a small amount of RF I/O circuitry. Surely, then, the rise of software-defined radio (SDR) ...

The transition from analog to software-defined radio (SDR) represents a significant advancement in communication technology. Traditional analog systems rely heavily on fixed hardware for signal ...

Software defined radio has become a staple of the RF tinkerer, but it’s likely that very few of us have ever taken their software defined toolchain outside the bounds of radio. It’s an area explored ...

With the advent of software defined radio platforms in military aerospace and now more recently in some consumer radio and electronics segments, the usefulness of Field programmable logic (FPGAs) as ...

SDR (software-defined radio) promises operators massive cost reductions. Cognitive radio will soon furnish bandwidth on demand. SDR forces re-evaluation of superhet and direct-conversion technologies.
