В системах цифровой связи широко применяются сигналы, построенные на основе ансамблей кодовых последовательностей. При разработке этих систем наибольшее внимание уделяется анализу, синтезу и реализации ансамблей периодических сигналов. Разработаны и используются теоретические методики синтеза ансамблей периодических сигналов. Значительно меньше результатов получено в области построения ансамблей апериодических сигналов с заданными корреляционными свойствами. Теоретические методики синтеза таких ансамблей сигналов практически отсутствуют.</p></sec><sec><title>Цель работы</title><p>Цель работы.

В статье описан алгоритм формирования полных и неполных минимаксных ансамблей апериодических кодов Голда с заданными длиной и объемом ансамбля. Приведены параметры и вид авто- и взаимнокорреляционных функций для ряда полученных ансамблей.

Разработанные алгоритмы, в отличие от известных, позволяют конструировать как полные ансамбли, так и ансамбли, учитывающие ограничение их объема. Кроме того, данные алгоритмы могут быть распространены на задачи построения ансамблей из других семейств, например, собранных из кодовых последовательностей, принадлежащих различным семействам.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Signals constructed on the basis of ensembles of code sequences are widely used in digital communication systems. During development of such systems, the most attention is paid to analysis, synthesis and implementation of periodic signal ensembles. Theoretic methods for synthesis of periodic signal ensembles are developed and are in use. Considerably fewer results are received regarding construction of aperiodic signal ensembles with given properties. Theoretical methods for synthesis of such ensembles are practically nonexistent.</p></sec><sec><title>Aim</title><p>Aim. To construct aperiodic Gold code ensembles with the best ratios of code length to ensemble volume among the most known binary codes.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Methods of directed search and discrete choice of the best ensemble based on unconditional preference criteria are used.</p></sec><sec><title>Results</title><p>Results. Full and truncated aperiodic Gold code ensembles with given length and ensemble volume were constructed. Parameters and shape of auto- and mutual correlation functions were shown for a number of constructed ensembles. Comparison of the paper results with known results for periodic Gold code ensembles has been conducted regarding growth of minimax correlation function values depending on code length and ensemble volume.</p></sec><sec><title>Conclusion</title><p>Conclusion. The developed algorithms, unlike the known ones, make it possible to form both complete ensembles and ensembles taking into account the limitation of their volume. In addition, the algorithms can be extended to the tasks of forming ensembles from other families, for example, assembled from code sequences belonging to different families.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>апериодические последовательности Голда</kwd><kwd>минимаксные ансамбли</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aperiodic Gold code sequences</kwd><kwd>minimax ensembles</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">Spreading Sequences in Active Sensing: a Review / E.
