Abstract

"APARELHO DE TRANSMISSãO SEM FIO E MéTODO DE SELEçãO DE ESQUEMA DE MODULAçãO". A presente invenção refere-se a um aparelho de transmissão sem fio que pode de forma precisa selecionar um esquema de modulação ótimo em uma base por bloco em um sistema e comunicação com múltiplas portadoras no qual a divisão por bloco de subportadoras e a modulação adaptável são executadas. Neste aparelho de transmissão sem fio, uma seção de aquisição de características de caminho de propagação (107) adquire a SNR média e a dispersão SNR para cada bloco, as quais são estimadas por um aparelho de recepção sem fio (200), utilizando sinais recebidos informados a partir de uma seção de recepção RF (106) e emite estes para uma seção de designação (108), a seção de designação (108) seleciona um esquema de modulação para cada bloco baseado na SNR média e na dispersão SNR de cada bloco informadas a parir da seção de aquisição de características de caminho de propagação (107), e as seções de modulação (101-1, 101-2, .... 101-L) modulam sinais de múltiplas portadoras incluídos em cada bloco, com o esquema de modulação para cada bloco selecionado pela seção de designação (108).
