Abstract

<B>MéTODO E APARELHO PARA IMPLEMENTAçãO DE DIVERSIDADE PARA UMA UNIDADE DE COMUNICAçãO DE MODO DUPLO<D> A presente invenção propicia um método para implementar diversidade para uma unidade de comunicação de modo duplo em um sistema de comunicação. O sistema de comunicação inclui um primeiro transceptor que utiliza uma primeira interface de ar e um segundo transceptor que utiliza uma segunda interface de ar distinta da primeira interface de ar. O sistema também inclui um controlador que inclui uma função seletora. A unidade de comunicação de modo duplo transmite uma primeira cópia de dados de portador para o primeiro transceptor utilizando a primeira interface de ar. A unidade de comunicação de modo duplo transmite uma segunda cópia dos dados de portador para o segundo transceptor utilizando a segunda interface de ar. O primeiro transceptor e o segundo transceptor enviam a cópia dos dados de portador para o controlador. O primeiro transceptor e o segundo transceptor também enviam uma métrica de qualidade para o controlador. O controlador seleciona uma cópia preferida dos dados de portador com base pelo menos em parte nas métricas de qualidade.
