Abstract

"MULTIPLEXAçãO POR DIVISãO DE FREQüêNCIA DE MúLTIPLOS FLUXO DE DADOS EM UM SISTEMA DE COMUNICAçãO MULTIPORTADORA SEM FIO". São descritas técnicas para multiplexar múltiplos fluxo de dados usando multiplexação por divisão de freqüência (FDM) em um sistema OFDM. São formados M 'entrelaçamentos' separados ou desligados com U sub-bandas utilizáveis. Cada entrelaçamento constitui um conjunto diferente de S sub-bandas, em que as sub-bandas para cada entrelaçamento estão entrelaçadas com as sub-bandas para cada um dos outros entrelaçamentos. Podem ser definidas M partições para cada período de símbolos, que recebem os índices de partição 1 a M. Os índices de partição podem ser mapeados para entrelaçamentos de tal forma que (1) seja obtida diversidade de freqüência para cada índice de partição e (2) os entrelaçamentos usados para transmissão de piloto possuem distâncias variáveis para os entrelaçamentos usados para cada índice de partição, o que melhora o desempenho de estimativa de canal. Cada fluxo de dados pode ser processado na forma de pacotes de dados de um tamanho fixo e diferentes números de partições podem ser usados para cada pacote de dados, dependendo do esquema de modulação e codificação usados para o pacote de dados.
