Abstract

"MéTODO E EQUIPAMENTO PARA UM TRANSMISSOR DE MúLTIPLA MODULAçãO". Um equipamento transmissor de modulação dupla (100) inclui um primeiro (134), um segundo (136) e um terceiro (132) percursos de sinal. O primeiro percurso de sinal inclui um modulador polar (120) acoplado a uma entrada de dados (115). O segundo percurso de sinal inclui um modulador em quadratura (122) acoplado à entrada de dados. O terceiro percurso de sinal é acoplado a uma antena (142) e inclui um comutador (128) configurado para acoplar o terceiro percurso de sinal ao primeiro percurso de sinal em uma primeira condição e para acoplar o terceiro percurso de sinal ao segundo percurso de sinal em uma segunda condição. Deste modo, o equipamento transmissor usufrui do melhor de ambos os mundos, uma vez que utiliza a modulação em quadratura ou a modulação polar nas circunstâncias mais apropriadas.
