Abstract

<B>MéTODO DE TRANSFERêNCIA EM UM SISTEMA DE COMUNICAçãO CDMA UTILIZANDO CóDIGOS WALSH E CóDIGOS QUASI-ORTOGONAIS<D> Um método de transferência em um sistema de comunicação CDMA utilizando códigos Walsh e códigos quasi-ortogonais. Para implementar uma transferência, uma nova estação base para a qual a chamada é comutada notifica uma estação base servidora de um código quasi-ortogonal disponível, se a nova estação base não tiver códigos Walsh disponíveis. A estação base servidora transmite uma mensagem de direção da transferência a uma estação móvel e a estação móvel comunica com a nova estação base utilizando o código quasi-ortogonal incluído na mensagem de direção da transferência.
