ABSTRACTS. Polonskyi K.V. Methodology of optimal reception of multipath signals under the influence of interchannel interference in OFDM telecommunication systems - Qualification scientific work on the rights of a manuscript. The thesis solves an urgent scientific and technical problem of improving the efficiency of receiving multipath signals under the influence of interchannel interference in telecommunication data transmission systems based on OFDM signal. The paper considers the peculiarities of the functioning of a telecommunication network based on parallel data transmission and frequency division signals with phase modulated signal multiplexing - OFDM (Orthogonal Frequency-Division Multiplexing). In the process of theoretical research and modeling, the following new scientific results were obtained in the dissertation, namely: - An improved model for calculating the power of interchannel transient interference in a telecommunications data transmission system based on OFDM signals; - For the first time, a methodology for selecting OFDM signal parameters under the influence of interchannel transient interference was developed; - The method of optimal reception of multi-position signals in a telecommunication data transmission system based on OFDM technology was improved. The practical significance of the results obtained in the field of development and creation of telecommunication systems is that the model proposed in the thesis and the methodology created on its basis can become the basis for the formation and creation of practically realized reception schemes.
