Abstract
"SISTEMA E MéTODO RECEPTOR DE VáRIAS DERIVAçõES".Um receptor proporciona sinais analógicos recebidos a váriasderivações de canal, e em pelo menos uma das derivações decanal, a freq³ência dos sinais analógicos recebidos é ajustadaindependentemente das posições relativas dos sinais analógicoscorrespondentes no espectro de freq³ência de rádio (RF). os sinaisanalógicos nas derivações de canal são então combinados, e ossinais analógicos combinados são convertidos para o dominiodigital. Por exemplo, o receptor compreende pelo menos umaantena (ou antenas) que recebe sinais analógicos de freq³ênciade rádio (RF). Um arranjador de derivação de canal recebe ossinais analógicos de (RF) da(s) antena(s) e fornece os sinaisanalógicos de RF a várias derivações de canal. Um arranjo deconversão de freq³ência que compreende pelo menos umconversor de freq³ência em pelo menos uma derivação entre asderivações de canal ajusta a banda de freq³ência dos sinaisanalógicos de RF na derivação de canal respectiva independentedas posições relativas dos sinais analógicos correspondentes noespectro de RF das derivações diferentes de canal. Os sinaisanalógicos nas derivações de canal são combinados, e um únicoconversor analógico/digital converte os sinais analógicoscombinados em sinais digitais. Ao converter os sinais analógicoscompostos para o domínio digital, as bandas de freq³ência dossinais analógicos são posicionadas em diversos canais de zonaNyquist no domínio digital. Através da seleção adequada dasbandas de freq³ência para os sinais analógicos nas derivações decanal e da taxa de amostragem para o conversor A/D, a largura debanda disponível para o conversor A/D pode ser usada maiseficientemente, e/ou coerência de tempo e/ou coerência de fasepodem ser providas.
