Аннотация. В статье рассматривается возможность применения одночастотных сетей (SFN) на базе LTE-1800 TDD для железнодорожного транспорта. Оцениваются преимущества и ограничения SFN при использовании на высокоскоростных магистралях. Методика включает аналитическое моделирование многолучевого канала (4 ответвления), анализ требований стандартов 3GPP и архитектурных сценариев оборудования BBU/RRU. Показано, что SFN повышает отношение сигнал/шум в зоне перекрытия, сглаживает «границы сот» для широковещательных сервисов, но жестко ограничен длиной циклического префикса и др. Установлено, что в LTE работоспособная SFN практически реализуема в пределах одного BBU.

Abstract. The article considers the possibility of using single-frequency networks (SFN) based on LTE-1800 TDD for railway transport. The advantages and limitations of SFN when used on high-speed highways are evaluated. The methodology includes analytical modeling of a multipath channel (4 branches), analysis of the requirements of 3GPP standards and architectural scenarios of BBU/RRU equipment. It is shown that SFN increases the signal-to-noise ratio in the overlap zone, smoothes the «cell boundaries» for broadcast services, but is strictly limited by the length of the cyclic prefix, etc. It has been established that in LTE, a workable SFN is practically feasible within a single BBU.
Keywords: LTE-1800 TDD, railway transport, SFN, radio communications, radio network design
