Abstract

"MéTODO DE REAMOSTRAGEM NA TRANSMISSãO E RECEPçãO DE UM SINAL DIGITAL COM TRADUçãO DA FAIXA DIGITAL". A presente invenção refere-se a um método de reamostragem (estimativa de probabilidades) na transmissão e recepção de um sinal digital com tradução de faixa digital. De acordo com a invenção, um procedimento de reamostragem (25) é executado após a recepção de um sinal da faixa de passagem, em que o sinal é traduzido (4) para uma faixa de base com uma freqüência configurável e o resultante sinal da faixa de base é introduzido em um dispositivo decimalizador (5) . Além disso, é executado um procedimento de reamostragem (26) após a transmissão, pelo que o sinal da faixa de base é interpolado (10) e, em seguida, traduzido para a faixa de passagem (20) com uma freqüência configurável. O método da invenção pode ser usado para corrigir o erro de freqüência introduzido pelos conversores digital-analógico (11) e analógico-digital (1). Além disso, o conjunto formado pela tradução da faixa e o acima mencionado procedimento de reamostragem podem ser usados para simplificar a complexidade dos filtros de interpolação usados para gerar novas leituras do sinal digital.
