Abstract

"APARELHO DE COMUNICAçãO SEM FIO E MéTODO DE MULTIPLEXAçãO DE DADOS". A presente invenção refere-se a um aparelho de transmissão sem fio capaz de aperfeiçoar a característica de recepção em uma extremidade de recepção de fluxo de dados. Neste aparelho, cada uma das partes de separação l/Q (110,112) separa os primeiros símbolos modulados de dados incluídos em qualquer pluralidade de fluxos de dados, que serão multiplexados, nos primeiros componentes em fase e nos primeiros componentes ortogonais, enquanto separa os segundos símbolos modulados de dados incluídos em outra pluralidade de fluxos de dados nos segundos componentes em fase e nos segundos componentes ortogonais. Uma parte de conversão l/Q (114) converte o primeiro componente em fases para os terceiros componentes ortogonais, enquanto converte os segundos componentes ortogonais nos quartos componentes em fase. A multiplexação por múltiplos códigos multiplexa os primeiros e os terceiros componentes ortogonais para fornecer um primeiro sinal multiplexado, enquanto multiplexa por múltiplos códigos os segundos e os quartos componentes em fase para fornecer um segundo sinal multiplexado. Uma parte de combinação l/Q (124) combina os primeiros e os segundos sinais multiplexados para fornecer um sinal combinado.
