Abstract
MéTODO PARA OBTENçãO DE INTERVALOS ESPECTRAIS NA TRANSMISSãO DE SINAIS EM UMA REDE ELéTRICA A presente invenção refere-se a um método para obtenção de intervalos espectrais na transmissão de sinais em una rede elétrica. O método permite que sinais a serem transmitidos em uma rede elétrica com uma adequada densidade espectral de potência, tal que a densidade espectral de potência seja ajustada para situações de regulação existentes com a possibilidade de os intervalos espectrais serem introduzidos na transmissão de uma maneira eficiente. A invenção é caracterizada por compreender o ajuste da potência de uma ou mais portadoras de sinal OFDM para a geração dos intervalos acima mencionados, o uso de TDFT<39>s de pelo menos 1024 pontos (se a IDFT for complexa) ou pelo menos 2048 pontos (se for uma TDFT real), e o uso de uma janela que multiplica os símbolos a serem transmitidos no tempo.
