Shipboard Communications Systems And The Research Of Key Technologies

Of modern naval warfare units in the war and more and more platforms, but with the constant development of technology.dependence of information between the various systems are also increasing, These near-explosive growth of information in the war led to the increased flow of information among various systems to collect, Optimization of real-time and accurate information and the ability to handle the higher demand. Ship communications systems by the current restrictions on the original system, it exposed a lot of skills shortages are no longer suited to the demands of the new era sea battle. Papers to understand and analyze in detail the characteristics and requirements of the exclusive carrier communication system, considered market, technological trends and the current level of technology, the paper presents a standardized, compact transmission, access, MSTP exchange system integration framework. New integration in the framework of the original external communications subsystem, radar, navigation, electronic warfare, acoustic, electro-optical, weapons and equipment, damage control.communications and command decisions, and other sub-systems integrated into a whole, to achieve a true sense of control, the integration of transmission.Based the design and implementation of a built-in shipboard communications systems Video Monitoring Program and the design and implementation of SDH overhead management of the DCC hardware transmitted, and TMN and SNMP interoperability of key technologies: Plug-in Network Management Architecture. Shipboard communications systems on the overall framework and network topology, network protection, network management technology, Video signal processing and speech signal processing of key technologies conducted in-depth research. Work and innovation are proposed:(1) A standardized compact transmission, access, MSTP integrated framework for the exchange system is designed and implemented.A distributed multi-concentration of population and the combination of regular cross-transmission structure,Tangent has supported the many different topologies such as a standard application (2) Generic slot independent bus concept Narrow band access mixed solution of the wide variety of design.High / low level separationspace-time matrix combined with the capacity of the cross-matrix(3) Speech enhancement algorithm based on human ears perceived Masking, Bark noisy voice combined with the minimum energy statistical estimates on a low signal-to-noise ratio channel(4) Speech recognition algorithm based on partial regression neural network (Locally Recurrent)...
