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) ...

There is a new breed of RF receivers known as software-defined radios, and they are revolutionizing the way in which people listen to shortwave (SW) radio, or indeed any form of radio broadcast. SDRs ...

Dallas, Texas — The TMS320C6418 digital signal processor (DSP) is optimized for telecom and software-defined radio applications. Features include 512 Kbytes of L2 memory, a Viterbi coprocessor (VCP), ...

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 ...

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 ...

One of the best ways to learn about radios is to build your own, even in the age of cheap SDR dongles. [Aniss Oulhaci] demonstrates this with a simple HF SDR receiver built on a breadboard. An Arduino ...

Overview of software-defined radio principles and an introduction to modern cognitive radio techniques. Fig 1. A conventional legacy radio receiver (a) uses the standard analog superheterodyne ...
