Abstract

DISPOSITIVO DE TRANSMISSãO SEM FIO, DISPOSITIVO DE RECEPçãO SEM FIO E MéTODO DE ARRANJO DE SìMBOLO. Um dispositivo de transmissão sem fio habilitado para melhorar uma performance de taxa de erro em um receptor, pela aquisição de pelo menos um efeito de diversidade de freqüência e um efeito de diversidade de tempo enquanto se mantém a resistência à interferência a qual é adquirida por difusão. Neste dispositivo de transmissão, uma unidade de modulação (101) modula dados para a criação de um símbolo de modulação que tem componentes em fase e componentes em quadratura. Uma unidade de difusão individual de IQ (102) arranja os chips de difusão, os quais são obtidos pela difusão do símbolo de modulação, das componentes em fase e das componentes em quadratura. Uma unidade de combinação de IQ (103) combina os chips de difusão dispostos das componentes em fase e das componentes em quadratura.
