Abstract
numerologias diferentes podem ser usadas para comunicar sinais baseados em multiplexação de divisão de frequência ortogonal (ofdm) em diferentes sub-bandas de frequência de um determinado portador. isso pode permitir que os sinais baseados em ofdm suportem eficientemente diversos tipos de tráfego. em algumas formas de realização, a numerologia do sinal baseado em ofdm depende de uma largura de banda da sub-banda de frequência sobre a qual os sinais baseados em ofdm são transmitidos. em algumas formas de realização, os sinais baseados em ofdm são sinais de ofdm filtrados (f-ofdm) e o filtro digital de modelagem de impulsos usado para gerar os sinais f-ofdm permite que o receptor mitiga a interferência entre sinais adjacentes de f-ofdm sob recepção, permitindo assim que sinais f-ofdm sejam comunicados em portadores consecutivos sem depender de uma banda de proteção.
