Abstract

Системы и способы позволяют получать данные ячейки в системе беспроводной связи в режиме работы с множественным доступом с частотным разделением каналов. Кодовые последовательности, переданные по основному каналу синхронизации (P-SCH), обеспечивают возможность детектирования границы символа, длительности циклического префикса и обозначения полосы пропускания канала широковещательной передачи. Последовательности, переданные по вторичному каналу синхронизации (S-SCH), обеспечивают возможность детектирования границы радиокадра, идентификации ячейки и обозначения полосы пропускания канала широковещательной передачи.
