Abstract

MéTODO E APARELHO PARA A DISPOSIçãO DE TONS DE PILOTO EM UM SISTEMA DE COMUNICAçãO MóVEL. Um aparelho e um método são providos para a disposição de tons para isolamento de sinais entre estações bases (BSs) em um sistema de dados de pacote de taxa alta (HRPD). Os dados de pacote são recebidos a partir de uma camada mais alta e os dados de pacote recebidos têm o canal codificado e são modulados. Tons de guarda são inseridos em simbolos dos dados de pacote modulados. Tons de piloto são inseridos usando-se arranjos de tom de piloto com base em deslocamentos de tom de piloto pré-regulados. Os simbolos de dados de pacote aos quais os arranjos de tom de piloto foram aplicados são espalhados, de modo que as BSs para transmissão de conteúdos de difusão diferentes sejam distinguidas umas das outras. Um prefixo cíclico (CP) é inserido após a realização de uma transformada de Fourier inversa nos simbolos de dados de pacote espalhados, e os simbolos são transmitidos.
