Abstract
Розглянуто сучасні різновиди амплітудно-фазової модуляції. Наведено сигнальні
сузір’я сучасних відомих та запропонованих нових різновидів амплітудно-фазової модуляції.
Розглянуто принципи побудови засобів для формування й оброблення запропонованого
високоефективного різновиду амплітудно-фазової модуляції – амплітудної
модуляції багатьох складових (АМБС). Запропоновано структурну схему високоефективної
телекомунікаційної системи на основі АМБС.
In today’s conditions of rapid development of information technology, the requirements for the speed of the transmission of information by such systems are increasing. In this case, it is necessary to ensure the minimum error probability and maximum efficiency in the process of transmitting information in conditions of interference. The occurrence of errors in the transmission of information is influenced by the methods used in the system for the formsng and processing of signals, in particular selected types of signal modulation and correcting coding. In this paper modern types of amplitude-phase modulation are considered. The signal constellations of modern known and proposed new types of amplitude-phase modulation are presented. The principles of construction of means for formsng and processing of the proposed highly effective variety of amplitude-phase modulation – amplitude modulation of many components (AMMC) are considered. The indexes of technical efficiency of telecommunication systems are studied in the application of known and new proposed types of signal modulation. The advantages of the means for forming and processing AMMC-signals compared to known means for forming amplitude-phase-modulated signals are shown. A structural scheme of a high-performance telecommunication system based on AMMC is proposed. This system uses digital-to-analog signal formsng in the transmitter and analogue-digital signal processing in the receiver.
