Alternatively, each radio connects to a geolocation database to obtain information about the spectrum occupancy in its location and, flexibly, adjusts its operating frequency and/or transmit power not to cause interference to other wireless services. Cognitive radio techniques: each radio measures the spectrum in use and communicates that information to other cooperating radios, so that transmitters can avoid mutual interference by selecting unused frequencies.

#Sdr receiver radio module software

Software defined antennas adaptively 'lock onto' a directional signal, so that receivers can better reject interference from other directions, allowing it to detect fainter transmissions.

Spread spectrum and ultrawideband techniques allow several transmitters to transmit in the same place on the same frequency with very little interference, typically combined with one or more error detection and correction techniques to fix all the errors caused by that interference.Ī software-defined radio can be flexible enough to avoid the 'limited spectrum' assumptions of designers of previous kinds of radios, in one or more ways including: SDRs, along with software defined antennas are the enablers of the cognitive radio. In the long term, software-defined radios are expected by proponents like the Wireless Innovation Forum to become the dominant technology in radio communications. Software radios have significant utility for the military and cell phone services, both of which must serve a wide variety of changing radio protocols in real time.

Such a design produces a radio which can receive and transmit widely different radio protocols (sometimes referred to as waveforms) based solely on the software used. Significant amounts of signal processing are handed over to the general-purpose processor, rather than being done in special-purpose hardware ( electronic circuits). While the concept of SDR is not new, the rapidly evolving capabilities of digital electronics render practical many processes which were once only theoretically possible.Ī basic SDR system may consist of a personal computer equipped with a sound card, or other analog-to-digital converter, preceded by some form of RF front end. mixers, filters, amplifiers, modulators/ demodulators, detectors, etc.) are instead implemented by means of software on a personal computer or embedded system. We are committed to providing outstanding product reliability and support, so you can focus on mission success.Software-defined radio ( SDR) is a radio communication system where components that have been traditionally implemented in analog hardware (e.g. The PicoFlexor Transceiver is backed by a standard three year warranty (some restrictions may apply). This customization enables the unit to perform in systems for both military and commercial operations including electronic attack, situational awareness, geo-location and spectrum monitoring. With its open SDR architecture, the PicoFlexor Transceiver can be configured using open frameworks, such as GNU Radio and REDHAWK, to fit customer-specific application requirements. In a miniature, tactical software-defined radio (SDR) platform, the PicoFlexor Transceiver integrates a transmitter with a high-performance SIGINT superheterodyne receiver in a single, low size, weight and power module. Equipped with the high performance parameters of the PicoFlexor, the PicoFlexor Transceiver adds a transmit capability.
