Abstract
Patente de Invenção: "MéTODO E EQUIPAMENTO PARA CORREçãO DO OFFSET DE FREQuêNCIA". A detecção coerente de comunicações digitais sem fio de alta velocidade se torna mais dificil quando as freq³ências dos osciladores do transmissor e do receptor não coincidem. Um loop travado em freq³ência (frequency-locked loop) pode ser usado para caracterizar tal offset de freq³ência pelo processamento das amostras recebidas em um canal piloto. Em lugar de usar as informações de offset assim derivadas para corrigir a freq³ência do sinal recebido, a invenção propicia economias consideráveis de computação pela aplicação de uma correção de freq³ência às amostras de piloto desespalhado.
