YEAST DISPLAY--CELL SURFACE PRESENTATION OF PROTEINS

Not Available The Backtalk airlink, developed for AJ/LPI communications in intraflight communication systems, is applied here to broadband multipoint data distribution in the U-NII and LMDS bands. The resultant airlink, referred to here as the Terrace system, employs a novel stacked-carrier multiple access (SCMA) communications format, blind adaptive reception, retrodirective transmission (smart airlines), (optional) smart antennas, and multihop network topologies to optimally exploit the spatial and spectral diversity present in Army communication networks. The resultant airlink can adaptively separate fixed and mobile in-cell nodes operating in the same frequency band, and can remove jamming encountered by the network during the reception process. Each Terrace node can also adaptively direct energy away from other Terrace nodes and jammers during transmission operations, allowing the network to continuously optimize its capacity and present minimal energy to other radios operating in the Terrace band. The airlink also incorporates simple means for removing features that could allow the link to be intercepted during the transmission process. The Phase I project will develop a Terrace concept, architecture, and rough cost estimate optimized for the LMDS band, and will validate performance using propagation data and testbeds provided by the Virginia Polytechnic Institute, a license holder in the LMDS band. BENEFITS: Potential near-term (LMDS) applications include broadband wireless
