ADAPTATION OF INFORMATION AND TECHNICAL CHARACTERISTICS TO THE CONSTANTLY CHANGING PARAMETERS OF IONOSPHERIC PROPAGATION
Abstract
The aim of the research work was to study and select the existing adaptation options for transmission parameters, in order to reduce the influence of shortcomings of the short-wave radio line, it is advisable to use the methods of digital signal processing as efficiently as possible. According to the results of the characteristics of analog-to-digital converters (ADCs), it became a study of the available hardware for constructing extended radio links, it was concluded that with an increase in the performance of FPGAs on which digital signal processing is implemented, it is possible to implement the technology of creating an active antenna array (AAR), consisting of the Nth number of independent antenna modules, which is a conceptual task in solving the issue of adapting information and technical characteristics to constantly changing parameters of ionospheric transmission, for a more energy-efficient approach to designing an ionospheric radio communication system. Improving the performance of the radio system by improving communication protocols, solving the problem of optimal channel load from the time of formation and reception of signals. The main idea of such an AAR is to digitize or generate a high-frequency signal in the immediate vicinity of the antenna, as part of the antenna modules. The indicated results make it possible to replace separately tuned radios and transceivers built according to a complex superheterodyne circuit with a limited number of available hardware units operating under software model of a software-configurable radio channel. In the next work, it is planned to conduct studies to assess the passage of OFDM signals through multipath communication channels with fading of Rayleigh and Rice. The resulting model will allow us to evaluate the noise immunity at different lengths of the cyclic prefix of the OFDM symbol and to observe the behavior of the signal constellation under the influence of various instabilities.
