Frequency and phase modulation systems are notoriously touchy, which is unfortunate since they tend to reject noise much better than pretty much any competing technology. Keeping these modes of communication in phase can be rather difficult, which is why a group of data scientists in Rolling Meadows, Illinois have developed a new method of keeping software defined radio modules in phase.
Miniaturized devices, such as the unit, are supposed to interface with commodity PC hardware. They’re normally not much thicker than a few silicon wafers. Traditionally, this means that they’re susceptible to quite a deal of interference. Using newer phase coherent SDR technology, operators can keep their transmissions within a specific set of tolerances.
This makes it possible to use even the smallest devices for sophisticated data transmissions. Specialists who had to use large purpose-built modules in the past can instead rely on a small software-based unit to take care of the job. Perhaps most important is the fact that a single phase coherent SDR circuit can tune a huge cross-section of the electromagnetic spectrum.
VHF frequencies were long seen as the best channels for longer range communications. Meanwhile, microwave ones were preferred by those who had to cut down on the amount of noise that they were exposed to. A single software defined board can support both of these bands, which make them an attractive option for a wide array of scenarios.
