Nooh T. Improving communication system LTE-Advanced

Object - operation of digital radio communication system LTE-Advanced based on multielement antennas in a МІМО environment. Purpose - development of methods to improve parameters of quality of digital radio communication system LTE-Advanced with МІМО, that is base on forming most stronger from the point of view of relation signal to noise ratio (SNR) of the own independent spatial channels adapted taking into account a channel state information (CSI). Methods - mathematical tool of electrodynamics and radio wave propagation theory, antenna theory, optimization theory, probability theory, methods of space-time and space-frequency signal processing. Results - a new method to increase the capacity in digital radio communication system LTE-Advanced with МІМО: method of dynamic continuous locked feedback loop; capacity modeling in the own independent spatial channels of digital radio communication system LTE-Advanced with МІМО has been performed to deliver a new result indicating that adaptation taking into account CSI is advantageous mostly at low SNR values; new advanced features have been developed to increase the capacity by means of reduction of interelement spacing in multielement antennas in a МІМО environment. Implementation - in research activity at KNURE and in the training course "Networks and Radio Access Systems" at KNURE. Application - telecommunication systems
