Abstract

"APARELHO DE TRANSMISSãO DE RáDIO, APARELHO DE RECEPçãO DE RáDIO E MéTODO DE TRANSMISSãO DE RáDIO". A presente invenção refere-se a um aparelho de transmissão de rádio capaz de melhorar o efeito de diversidade. Neste aparelho, uma seção de rotação de fase (102) executa um processamento de rotação de fase de 40,6<0> = 26,6<0> + 14,0<0>, os intercaladores (106, 111) executam um processamento de intercalação de duas vezes antes do processamento de combinação de IQ executado em uma seção de combinação (107) e após o processamento de separação de IQ executado em uma seção de separação de IQ (108), e o símbolo de modulação original obtido em uma seção de mapeamento (101) é por meio disto disperso e mapeado para/em pontos de sinal de um nível de modulação M-ário mais alto em duas posições ou mais (por exemplo, de um símbolo de QPSK para símbolos de 256QAM).
