Abstract

Способ передачи символов данных через символы мультиплексирования с ортогональным частотным разделением сигналов (МОЧР) включает в себя следующее: формируют символы данных в пары, генерируют первую пару символов модуляции для каждой из пар символов данных, причем первая пара символов модуляции формирует первый и второй символы модуляции ячейки Аламоути, формируют первую версию символов МОЧР путем модуляции поднесущих, выделенных для переноса данных, первым и вторым символами модуляции ячеек Аламоути, и модулируют одну или больше пилотных несущих первой версии символа МОЧР в соответствии с заданной структурой. Способ также включает следующее: генерируют вторую пару символов модуляции для каждой из пар символов данных, причем вторая пара символов модуляции формирует третий и четвертый символы модуляции ячейки Аламоути, сформированной для пары символов данных в первой версии символа МОЧР, формируют вторую версию символа МОЧР путем модуляции поднесущих, выделенных для переноса данных с третьим и четвертым символами модуляции ячейки Аламоути, модулируют одну или больше пилотных несущих второй версии символов МОЧР в соответствии с заданной структурой и передают первую версию символа МОЧР через первую антенну и вторую версию символа МОЧР через вторую антенну. Для по меньшей мере одной из пар символов данных поднесущие, по которым каждый из первого и второго символов модуляции и третьего и четвертого символов модуляции формируют ячейки Аламоути, разделены в пределах первой и второй версий символа МОЧР по меньшей мере одной другой поднесущей, которая несет данные, или одной или больше пилотными несущими.
