Ilchenko, Registration Date 07-12-2011 Organization Research Institute of Telecommunications National technical university of Ukraine "KPI" popup.description2 Working out of principles of construction and methods of implementation of mobile broadband access systems of a millimeter wave band for maintenance of high-speed access of users to ІР-networks data transfers under condition of maintenance of the secured quality of giving of services was a research work main objective. Principles of construction of mobile systems broadband access of millimeter wave band are developed: architecture, topology, a support of mobility levels, means of maintenance of quality of giving of services, the organization of a basic network and an access network, interacting with existing networks of the general using and networks of a cellular vehicular communication. Parameters of OFDM-signals are developed for creation systems of millimeter wave band, optimum methods of modulation are chosen. Effective methods of adaptation to change of working conditions of mobile broadband access systems of millimeter wa ve band in the conditions of the multiple-beam wave propagation are developed. Synchronization methods in systems with OFDM-modulation are analyzed, optimum combinations of methods of coarse and exact tune are chosen and algorithms of synchronization and their prototypes in language VHDL are developed. On the basis of spent to the analysis and imitating modeling of new methods of antinoise coding, optimum computational algorithms of decoding convolution turbo-codes and procedures of their implementation in the form of prototypes in the programming language of high level C++ are developed. The imitation model to the channel of mobile broadband access system in the form of the software package of modeling of separate processes and the visually-oriented model is developed, allowing to model various processes of physical and channel levels in telecommunication systems of various complexities and behavior of wireless channels in the conditions of the multiple-beam wave propagation.
