Abstract
Описаны системы и методологии, которые упрощают переключение между разными комбинациями MIMO, SIMO, SISO и OFDM, LFDM и IFDM. Согласно разным аспектам, представленный способ для сети беспроводной связи, которая включает в себя: прием первого набора информации данных, причем первый набор информации включает в себя первое значение, определение того, является ли первое значение большим, чем пороговое значение, и передачу индикатора для переключения на использование первого метода передачи, если определено, что первое значение больше порогового значение.
