Ahmed J. Methods to improve noise immunity WIMAX wireless access systems

Object - the processes functioning systems WIMAX radio. Goal - improving immunity digital transmission of radio communications systems, WiMAX. Item - a model of electromagnetic interactions, electronic means and methods to ensure the conditions of electromagnetic compatibility and immunity systems WIMAX using space-time signal processing techniques. Methods - radio physics, theory of telecommunications, systems analysis, mathematical statistics, probability theory, optimization theory, the theory of estimation and control methods of space-time signal processing, mathematical modeling, simulation experiment. Results - for the first time to estimate the channel matrix procedure is proposed Kalman-Bucy. Improved non-orthogonal space-time codes with improved energy efficiency. For the first time management techniques proposed modification bagatoantennoi regime by technology WIMAX systems. Implemented - in Kharkov State Regional Science and Technology Center for technical protection of information, the learning process the department of telecommunications systems Kharkiv National University of Radio Electronics. Scope - wireless telecommunications systems.
