Abstract

resumo da patente de invenção para: “compensação on-the-fly de frequência de amostragem e deslocamento de fase no receptor realizando comunicação sem fio de velocidade ultra alta”. problema para restaurar dados de uma sequência de símbolos transmitida sem alinhar o relógio do receptor com o relógio do transmissor. solução os dados recebidos sobre amostrados duas vezes são polifaseados pelo receptor, o feedback é aplicado usando um algoritmo adaptativo, e os coeficientes de filtro (sequência de coeficiente de tap) de um filtro de compensação são simultaneamente deslocados quando os dados deslocam-se. a frequência de amostragem e o deslocamento de fase podem ser compensados em tempo real usando um filtro combinando um filtro afunilado, cujo valor inicial é um valor de correlação obtido a partir do preâmbulo e do cabeçalho de um sinal recebido, e um alinhador de frente de onda. nesta configuração, um circuito de filtro de reamostragem, um circuito de filtro de equalização e um circuito de filtro de dizimação são realizados em um único circuito de filtro de compensação, o que é muito menor do que os circuitos da técnica anterior, em termos de tamanho.
