Abstract

"MéTODO E APARELHO PARA A MODULAçãO HIERáRQUICA USANDO UMA CONSTELAçãO RADIAL". é provido um método para uma modulação hierárquica relativa a um primeiro sinal, um segundo sinal, e uma constelação original tendo uma pluralidade de símbolos em uma configuração de 8 Chaves de Deslocamento de Fase PSK) não uniforme. A modulação de Chaves de Deslocamento de Fase de Quadratura (QPSK) é usada para o primeiro sinal, e a modulação de Chaves de Deslocamento de Fase Binária (BPSK) é usada para o segundo sinal. O método inclui a etapa de substituir pelo menos alguns dentre a pluralidade de símbolos por pelo menos uma constelação de chaves QPSK-BPSK do tipo radial.
