Abstract

em um aparelho de comunicação, um modulador executa uma modulação ortogonal em um sinal de preâmbulo e em um sinal de cabeçalho de cada um dos dois canais adjacentes usados em uma transmissão de agregação, gerando desse modo dois sinais portadores únicos deslocados em faixas de frequência dos respectivos dois canais. um gerador de sinal ofdm executa um processo ifft coletivamente em sinais de carga útil dos dois canais adjacentes usados na transmissão de agregação, gerando deste modo os sinais ofdm dos dois canais. uma antena transmite os sinais ofdm dos dois canais.
