Abstract

"MéTODO PARA RASTREAMENTO DE CóDIGO DE DEDOS DE RECEPTOR RAKE, PROGRAMA DE COMPUTADOR, DISPOSITIVO DE MEMóRIA DE COMPUTADOR, E, RECEPTOR ARRANJADO PARA RASTREAR CóDIGO DE DEDOS DE RECEPTOR RAKE". Um método para rastreamento de código de dedos de receptor RAKE, em cujo método valores de retardo foram estabelecidos para os dedos do receptor RAKE, usando um método de aquisição de fase de código. O método compreende obter diversas amostras sucessivas de um sinal recebido, combinar valores de amostra medidos em diferentes dedos em conjuntos de valor de medição, comparar os conjuntos de valor de medição uns com os outros e selecionar o conjunto de valor de medição possuindo valor mais alto entre os conjuntos de valor de medição satisfazendo a uma condição de distância de retardo mínima para os dedos, se algum dos valores de amostragem do conjunto de valor de medição selecionado é mais adiantado que um valor de amostra no tempo determinado com base na aquisição de fase de código, avançar a fase de amostragem e/ou código do dedo particular, e se algum dos valores de amostra do conjunto de valor de medição selecionado é mais atrasado que o valor de amostra no tempo determinado com base na aquisição de código, retardar a fase de amostragem e/ou código do dedo particular.
