Abstract

"APARELHO E MéTODO PARA TRANSMISSãO E RECEBIMENTO DE DADOS EM UM SISTEMA DE COMUNICAçãO CDMA". é exibido um método para a atribuição de códigos ortogonais usados para um primeiro sistema e para um segundo sistema em um sistema de CDMA, incluindo canais do primeiro sistema para a difusão de um sinal piloto, um sinal de sincronização, um sinal de rádio-chamada e um sinal de tráfego, com um primeiro conjunto de códigos ortogonais correspondente aos números de código ortogonal nas diferentes linhas de um conjunto de códigos ortogonais dispostos em uma matriz de m linhas e m colunas, e canais do segundo sistema para a difusão de um segundo conjunto de códigos ortogonais correspondentes aos números de código ortogonal diferentes dos referidos números de código ortogonal para o primeiro conjunto de códigos ortogonais. Os códigos ortogonais para o segundo sistema são transmitidos a uma taxa de dados mais alta do que uma taxa de dados do primeiro sistema. O método compreende as etapas de: atribuição de códigos ortogonais correspondentes aos números de código ortogonal do conjunto de código ortogonal associado a pelo menos uma das segundas linhas aos canais do primeiro sistema, onde um conjunto de códigos ortogonais é disposto em uma matriz de subconjuntos de códigos ortogonais e códigos ortogonais inversos, cada subconjunto incluindo segundas linhas e segundas colunas; e atribuição de códigos ortogonais correspondentes aos números de código ortogonal do conjunto de código ortogonal associado a pelo menos uma das linhas remanescentes ao segundo sistema.
