Pulsed Non-coherent QPSK Low Probability of Intercept Waveforms for Commercial Software-Defined Radios

United States National Committee of URSI National Radio Science Meeting
Software-defined radios (SDRs) provide a quick way to modify a device's communication frequency, modulation, and functionality. This flexibility makes them a preferred choice for transceivers that require fast modification.
