The book "Effectiveness of modulation methods in digital radio communication systems", compiled under the editorship of Maglitsky B. N. and with the participation of authors such as Volkov A. A. , Chelyshkov P. D. and Sedov A. In. , is a real treasure for specialists in the field of radio communication and digital technologies. This publication will be an indispensable assistant for both undergraduate and graduate students, as well as for practicing engineers and researchers seeking to better understand modern modulation methods and their impact on data transmission efficiency. The book covers a wide range of topics related to signal modulation in digital radio communication systems. The authors analyze in detail various modulation methods, such as QAM (quadrature amplitude modulation), PSK (phase modulation) and OFDM (orthogonal frequency modulation), considering their advantages and disadvantages in real-world applications. The reader will be able to learn how to choose the best modulation methods depending on the transmission conditions, communication quality requirements and available resources. One of the key topics of the book is the analysis of the effectiveness of various modulation methods in the context of modern requirements for data transmission speed and immunity to interference. The authors not only present theoretical foundations, but also support their conclusions with practical examples and research results, which makes the material accessible and understandable to a wide audience. The reader will be able to see how theoretical concepts are applied in practice and what results they can bring. This book will be of interest not only to specialists in the field of radio communication, but also to everyone who is interested in digital technologies, telecommunications and information systems. Students of technical universities, graduate students, as well as practicing engineers will find here a lot of useful information that will help them in their studies and professional activities. In addition, the book can be useful for managers engaged in projects in the field of communication, as it gives an idea of modern trends and technologies. The style of the authors is distinguished by clarity and logical presentation, which makes it easy to assimilate even the most complex concepts. The book is saturated with graphs, tables and illustrations, which makes it visually attractive and facilitates the perception of information.
