Abstract

Описаны способы для выполнения скремблирования на уровне кодового слова для MIMO-Передачи. Передающая станция может выполнять канальное кодирование для множества потоков данных, которые одновременно передаются для MIMO-Передачи. Канальное кодирование может включать в себя FEC-Кодирование и/или согласование скорости. После канального кодирования передающая станция может выполнять скремблирование для множества потоков данных с помощью разных кодов скремблирования. После канального кодирования передающая станция также может выполнять перемежовывание канала, сравнение символов и пространственную обработку для множества потоков данных. Приемная станция может принимать МИМО-Передачу, выполнять дескремблирование для множества потоков данных с помощью разных кодов скремблирования и, далее, выполнять канальное декодирование для множества потоков данных. Скремблирование может позволить приемной станции изолировать каждый поток данных путем выполнения дополнительного дескремблирования, а также получать рандомизированные помехи от других потоков данных, что может улучшить производительность.
