Mircroarrays of Affinity Probes for the Analysis of Gene Products

Not Available This Phase 1 SBIR effort will build upon today's most advanced voice data coding algorithms to develop a selection of efficient, robust low data rate voice options for Link-16. JTIDS/MIDS terminals currently provide 16 KBPS CVSD and/or 2.4 KBPS LPC-10 algorithms which are time-proven voice coding techniques that have been superseded in quality by Mixed Excitation Linear Predictive (MELP) and Code Excited Linear Predictive (CELP) algorithms. This proposed Phase 1 effort will explore various levels of Error Detection And Correction (EDAC) encoding options used in conjunction with CELP and MELP algorithms to provide high quality, low data rate voice in the harsh communication environments required for Link-16. In order to add EDAC, additional network capacity will be required to accommodate the added parity data. To overcome the effects of increasing the bandwidth, this effort will investigate the combination of coded low data rate voice algorithms and Link-16 Enhanced Throughput (ET). ViaSat has developed Link-16 ET Technology which provides up to a factor of 10 improvement in data rate over existing JTIDS/MIDS so the combination of coded voice and ET will provide a very bandwidth efficient solution to the Link-16 voice problem.
