Abstract
DEMODULAçãO BASEADA EM SUB-BANDA UTILIZANDO TRANSFORMADA DE FOURIER REDUZIDA PARA UM SISTEMA DE COMUNICAçãO BASEADO EM OFDM Para demodulação OFDM baseada em sub-banda, uma transformada de Fourier "parcial" é realizada em uma sequência de N amostras de entrada para um símbolo OFDM para obter N~c~ símbolos recebidos para um grupo de N~c~ sub-bandas de dados, onde N~c~L=N e L>1. Para a transformada parcial de Fourier, as N amostras de entrada são giradas com um fasor para obter N amostras de entrada giradas, que são acumuladas (para cada conjunto de L amostras) para obter N~c~ valores de domínio de tempo. Uma FFT de ponto N~c~ é realizada nos N~c~ valores de domínio de tempo para obter os N~c~ símbolos recebidos. As estimativas de ganho de canal para as sub-bandas de dados também são obtidas, por exemplo, pela realização de uma transformada parcial de Fourier para obter os símbolos piloto recebidos, uma FFT inversa para obter os valores de ganho de canal de domínio de tempo, e uma FFT para obter estimativas de ganho de canal para as sub-bandas de dados. Os símbolos recebidos são processados com (por exemplo, equalizados por) as estimativas de ganho de canal para obter os símbolos de dados recuperados.
