Abstract

MéTODO PARA COMUNICAçõES DUPLEX, DISPOSITIVO DE COMUNICAçõES, SISTEMA COMPREENDENDO UM OU MAIS TRANSCEPTORES, PROGRAMA DE COMPUTADOR, E, MEIO PORTADOR Um método, um dispositivo e um sistema para comunicações duplex. Freqüências de enlace ascendente e enlace descendente são alocadas de uma maneira ortogonal, de tal modo que,em um instante de tempo, uma certa freqüência de portadora é usada para transmissão de enlace ascendente (enlace descendente) e em algum outro instante de tempo para transmissão de enlace descendente (enlaceascendente). Correspondentemente, no citado um instante de tempo, uma segunda freqüência de portadora é usada para transmissão de enlace descendente (enlace ascendente) e no citado algum outro instante de tempo, opcionalmente para transmissão de enlace ascendente (enlace descendente).
