Abstract

APARELHO DE TRANSMISSãO DE RADIO E MéTODO DE TRANSMISSãO DE RáDIO EM COMUNICAçãO COM MúLTIPLAS PORTADORAS. A presente invenção refere-se a um aparelho de transmissão de rádio onde consumo desnecessário de potência de transmissão pode ser suprido e a PAPR (Proporção de Potência de Pico para Média) pode ser reduzida na comunicação com várias portadoras. No aparelho, uma parte de repetição (105) replica (repete) cada símbolo emitido a partir de uma parte de modulação (103) para gerar e emitir uma pluralidade de símbolos idênticos para uma parte S / P (107), a qual converte a seqüência de símbolos emitida em série a partir da parte de repetição (105) para seqüências de símbolos paralelas e emite as mesmas para um intercalador (109). O intercalador (109) então reordena as seqüências de símbolo emitidas a partir da parte S / P (107) e emite as mesmas para uma parte de mapeamento (111), a qual remove, de acordo com a qualidade do caminho de propagação de cada uma das subportadoras constituindo os símbolos OFDM que são sinais com várias portadoras, alguns dos símbolos idênticos como replicados pela parte de repetição (105) e então mapeia o resto dos símbolos para subportadoras para aplicação para um parte IFFT (113).
