Investigation of the technical efficiency of state-of-the-art telecommunication systems and networks with limited bandwidth and signal power

Abstract

Certain widely used state-of-the-art, as well as newly suggested, types of signal modulation are studied. The proposed amplitude modulation of many components (AMMC) is characterized by a large Euclidean distance, higher noise immunity under the same maximum power and informativity of the modulated signal, or requires lower power of the modulated signal under the same noise immunity and informativity in comparison with the well-known amplitude shift keying (ASK), phase shift keying (PSK), and quadrature amplitude modulation (QAM). It is found that the technical efficiency of telecommunication systems and networks with limited bandwidth and signal power that use AMMC is overall higher in comparison with the other considered well-known types of modulation. In particular, 37-AMMC with 3 components is the most efficient type among the studied modulations with the number of symbols being up to 37.
