Hussam D. Improving communication quality LTE technology with МIMO based adaptive space-time coding method

Object - processes of functioning of LTE systems with physical level MIMO. Purpose - development of methods to improve communication quality LTE technology with MIMO based space-time coding method using adaptive modulation and space-time adaptive signal processing. Methods - telecommunication theory, probability theory, optimization theory, estimation and management theory, space-time signal processing, mathematical modeling, full-scale experiment. Results - It is proposed a new method for adaptive modulation in MIMO channels of LTE technology based on selection of a higher multiplicity of multipositional modulation in three-dimensional channels with a low attenuation level and a lower modulation multiplicity; improved the method of parameters estimation in MIMO channels based on Kalman filtering to ensure a higher quality and speed of estimation required fir adaptive selection of the type of multipositional modulation; method of space-time signal processing for technology LTE is proposed, based on using of adaptive antenna arrays with adaptation algorithm by the pilot signal. It is introduced - in the research scientific work № DR 0111U002627; used in learning process in the Kharkiv national university of radio electronics. Sphere of application - telecommunication systems
