Unitary Braid Division Multiplexing

Bascom Hunter Technologies, along with Rampart Communications, proposes a solution to the Navy's need forĀwaveforms that are truly featureless for resilient Low Probability of Detection (LPD) and Low Probability of Interception (LPI) links, without compromising reliability, throughput, or performance. This solution is called Unitary Braid Division Multiplexing 2.0 (or UBDM 2.0) and is built on proprietary work done by Rampart Communications called UBDM 1.0 and Mulligan. UBDM is a software/firmware solution that takes baseband IQ (which is typically an identifiable, analyzable, and potentially exploitable constellation pattern) and converts it into a Gaussian distribution of points. This makes is exceptionally difficult to detect and nearly impossible to intercept. With UBDM 1.0, detection is possible (but extremely unlikely) as pilots and other synchronization components of the signal are not transformed. With UBDM 2.0, all aspects of the waveform will be transformed, and the result is truly chaotic. In this Phase 2, we will demonstrate UBDM 2.0 with a next generationĀAll Digital Modem as well as existing SATCOM Modems.
