С развитием технологий мобильной связи ресурсов беспроводного спектра становится недостаточно. Исследователи ищут новые технологии мобильной связи, которые будут не только отвечать ожиданиям пользователей, но и улучшат эффективность беспроводного спектра. Ключевые технологии исследования беспроводной сети следующего поколения основаны на сложных алгоритмах управления множественным доступом на физическом уровне. В статье предлагается новый алгоритм гибкого множественного доступа (неортогонального множественного доступа, НОМД), анализируется производительность системы для НОМД восходящей линии связи с усовершенствованным приемником последовательного подавления помех, применяемым на стороне базовой станции. С помощью Matlab показывается, что производительность системы, достигнутая в НОМД, выше на 30 % по сравнению с системой ортогонального множественного доступа.

Although the specific technical standard of 5G has not been formulated yet at present.  However, spectrum efficiency will be a key developing direction for 5G wireless communication system from the research results which released by major international organizations. From this point of view, the nonorthogonal multiple access algorithm (NOMA) can satisfy both the demand rate and the spectral efficiency of mobile services.
