Abstract

"PESQUISADOR PROGRAMáVEL DE FILTRO CASADO PARA PESQUISA MúLTIPLA DE PILOTO". São descritos um método e um equipamento novos e aperfeiçoados para pesquisa. Tal pesquisador combina a capacidade de pesquisar múltiplos offsets de pilotos únicos, tais como aqueles encontrados no sistema IS-95, com a capacidade de pesquisar múltiplos pilotos, tais como aqueles encontrados em um sistema de determinação de localização GPS. Ambos os os tipos de pesquisa podem ser efetuados em uma única estrutura combinando os recursos de computação em paralelo de um filtro casado com a flexibilidade de permitir a execução de um número variável de acumulações não coerentes com alta velocidade para uma ampla gama de hipóteses de pesquisa de uma maneira eficiente em termos de recursos. A presente invenção permite o uso paralelo da estrutura de filtro casado de uma maneira temporalmente dividida para pesquisar múltiplas janelas. Além disso, o pesquisador permite a descoberta o decodificação Walsh independente opcional para cada janela de pesquisa. A estratégia de compartilhamento de tempo permite a pesquisa opcional de freq³ências de qualquer offset.
