Abstract

"APARELHO E MéTODO PARA DECODIFICAçãO EM UM SISTEMA DE MODULAçãO HIERáRQUICO". Um receptor de satélite recebe um sinal com base na modulação hierárquica, que tem pelo menos uma camada superior (UL) e uma camada inferior (LL), e simultânea ou independentemente recupera delas os dados transportados no sinal da UL e os dados transportados no sinal da LL.
