While most smartphones can receive at least some radio, transmitting radio signals is an entirely different matter. But, if you have an Android phone and a few antennas (and a ham radio license) it ...

This article describes the design flow for SCA-based SDR systems based on pre-integrated platform solutions. It examines each phase of the process from requirements definition through low level ...

In the last installment we looked at the ultrasonic hardware used in the development of a software designed ultrasonic data transmission system we are calling the SDU-X. In this second, and last, ...

Software defined radios (SDRs) can–in theory–do almost anything you need a radio to do. Voice? Data? Frequency hopping? Trunking? No problem, you just write the correct software, and you are in.

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) ...
