Abstract

Предложено сокращение процесса поиска соты, включающего в себя идентификацию сектора, без увеличения нагрузки на устройство передачи/приема. Канал синхронизации (канал SCH), включенный в нисходящую линию связи в системе мобильной связи с множеством несущих, умножается на индивидуальный для сектора код и индивидуальный для соты код (этап S1), назначается поднесущим на оси частот (этап S2), подвергается обработке расширения и обратного быстрого преобразования Фурье (IFFT) (этапы S3, S4) и затем подвергается вставке защитного интервала (GI) и цифроаналоговому преобразованию (этапы S5, S6), и сигнал с множеством несущих передается от направленной антенны каждого сектора (этап S1). Принимающая сторона определяет позицию канала SCH методом автокорреляции или методом взаимной корреляции, выполняет быстрое преобразование Фурье (FFT) и затем одновременно выполняет идентификацию сектора посредством детектирования индивидуального для сектора кода и получение индивидуальной для соты информации посредством демодуляции индивидуального для соты кода.
