Приводятся рекомендации по выбору индекса модуляции, оптимального с точки зрения минимальной вероятности битовой ошибки в многолучевом канале передачи данных. Получено аналитическое выражение для вероятности битовой ошибки для модуляции BPPM. Представлены графики зависимости вероятности битовой ошибки от отношения сигнал/шум для различных скоростей передачи данных, вычисленных с использованием аналитического выражения и полученных с помощью компьютерного моделирования в системе MATLAB.</p></abstract><trans-abstract xml:lang="en"><p>The impact of modulation index on the BER performance of BPPM in UWB radio is analyzed in multipath indoor channels. The recommendations for the optimal modulation index choice are drawn up with respect to minimum bit error rate in multipath indoor channel. The theoretical expression for BER performance of BPPM is derived. The BER performance figures for different data rates as a function of a signal to a noise ratio produced by using the theoretical expression and computer simulations are presented. MATLAB is used for computer simulations.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>короткоимпульсные сверхширокополосные системы радиосвязи</kwd><kwd>помехоустойчивость</kwd><kwd>индекс модуляции</kwd><kwd>двоичная позиционно-импульсная модуляция</kwd><kwd>BPPM</kwd><kwd>UWB</kwd><kwd>Indoor UWB</kwd><kwd>КСШП</kwd></kwd-group><kwd-group xml:lang="en"><kwd>short-pulse UWB radio system</kwd><kwd>BER (bit error rate) performance</kwd><kwd>modulation index</kwd><kwd>binary pulse position modulation</kwd><kwd>BPPM</kwd><kwd>UWB</kwd><kwd>Indoor UWB</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">Arslan H., Chen Z.
