Abstract

"DISPOSITIVO E MéTODO DE TRANSMISSãO E MEIO DE ARMAZENAMENTO". é possível transmitir preferivelmente um sinal de seqüência de tempo de um padrão conhecido como um preâmbulo e um sinal de modulação de OFDM. Em comunicação, pela definição de um preâmbulo e detecção de um pico da relação interativa, a sincronização pode ser detectada. O preâmbulo neste caso é definido frequentemente por um valor binário para simplificar um dispositivo detector de correlação. Neste caso, o espectro pode se torna irregular e a característica de correlação pode ser deteriorada. Nesta invenção embora mantendo a fase do espectro do padrão do preâmbulo no lado de transmissão a amplitude é forçada a ser ajustada deste modo melhorando as características de espectro e correlação ao mesmo tempo simplificando o dispositivo de detecção de correlação no lado de recepção.
