Abstract

diferentes formatos de quadros de multiplexação por divisão de frequência ortogonal filtrada (f-ofdm) podem ser usados para alcançar a flexibilidade do espectro. as formas de onda f-ofdm são geradas aplicando um filtro digital de modelagem de impulsos a um sinal de multiplexação por divisão de frequência ortogonal (ofdm). diferentes formatos de quadros podem ser usados para transportar diferentes tipos de tráfego, bem como para se adaptarem às características do canal, transmissor, receptor ou célula de serviço. os diferentes formatos de quadros podem utilizar diferentes espaçamentos de subportadora (sc) e/ou comprimentos de prefixo cíclico (cp). em algumas formas de realização, os diferentes formatos de quadros também utilizam diferentes durações de símbolos e/ou comprimentos de intervalo de tempo de transmissão (tti).
