Автором предложен метод моделирования и расчета характеристик спектральной плотности мощности стандартных цифровых тестовых электрических сигналов для различных способов линейного кодирования. В качестве моделей исходных (первичных) их образований использованы стандартные бинарные последовательности фиксированной и псевдослучайной структур. Как аналитический инструмент метод пригоден для исследования влияния линейного кодирования и форматов модуляции на качество передачи данных в высокоскоростных сетях транспортной связи.</p></abstract><trans-abstract xml:lang="en"><p>In communications technology for testing of digital channels and links are widely used digital signals with fixed and pseudorandom structures. The author proposes a method for simulating and analyzing the characteristics of the power spectral density of standard test digital electrical signals for different methods of linear coding. As models of their initial (primary) formations are used standard binary sequences of fixed and pseudorandom structures. As an analytical tool the method is suitable for studying the effect of the linear coding and modulation formats on the quality of data transmission in high-speed networks of transport links.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>техника связи</kwd><kwd>цифровые каналы</kwd><kwd>тестовые сигналы</kwd><kwd>тестовые последовательности</kwd><kwd>модель сигнала</kwd><kwd>спектральная плотность мощности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>communications technology</kwd><kwd>digital channels</kwd><kwd>test signals</kwd><kwd>test sequences</kwd><kwd>signal model</kwd><kwd>the power spectral density</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Рекомендация МСЭ-Т O.150.
