Patent
Time shift keying digital communications system
TL;DR: In this paper, a digital modulation technique is disclosed which is unique in that it does not utilize fixed time slots for varying the characteristics of an electromagnetic carrier signal, but actually uses variations of the time slots to transfer the digital information.
Patent
Cosine segment communications system
TL;DR: In this paper, a digital communication system with discrete cosine segments was disclosed, which is unique in that it modulates a sinusoidal carrier with discrete segments (fig. 13).
Patent
Burst mode digital communications system
TL;DR: In this paper, the bit edges of the discrete cosine segments are forced to occur at the zero slope points of a cosine wave, where no voltage changes occur, rather than employing the use of filters for controlling instantaneous voltage changes.
Patent
Method and system for modeling rf emissions occurring in a radio frequency band
TL;DR: In this paper, the authors present a method and system for modeling RF emissions occurring in a radio frequency band utilizing commercial off-the-shelf (COTS) hardware to perform the steps of converting legacy PDW databases to RF signal I and Q format.
Patent
Real time fiber optic matrix switch interconnection
TL;DR: In this article, a real time fiber optic matrix switch includes at least one matrix switch port and a controller card, which is configured to recognize communication protocols associated with any of the Type A-H and J signals of the Naval Tactical Data System (NTDS).
