Abstract

"APARELHO DE RADIOTRANSMISSãO E PROCESSO DE MAPEAMENTO DE SINAL DE TRANSMISSãO". Seção de transformação S/P 101a que transforma os dados de transmissão A de dados em série para dados paralelos, e emite os dados paralelos para a seção de mapeamento 16QAM 102 como dados a serem mapeados nos bits (S0 e S1) com qualidade relativamente alta. A seção de transformação S/P 101 b transforma os dados de transmissão B de dados em série para dados paralelos, e emite os dados paralelos à seção de mapeamento 16QAM 102 como dados a serem mapeados nos bits (S2 e S3) com qualidade relativamente baixa. A seção de mapeamento 16QAM 102 executa o mapeamento nos dados de transmissão A e B no diagrama de espaço de sinal de 16QAM por meio da Codificação de Gray. Depois, os dados de transmissão A e B passam pela modulação digital, sendo transmitidos a uma extensão de comunicação através da antena 105.
