Abstract

"MéTODO DE COMUNICAçãO COM PORTADORA MúLTIPLA". A presente invenção refere-se a um método para a comunicação entre estações de rádio dentro de um sistema de comunicação via rádio, sob a utilização de pelo menos uma banda de freqüência dividida em uma diversidade de sub-bandas (SB1, SB2, SB3, SB4). De acordo com a presente invenção, o modo de divisão da pelo menos uma banda de freqüência em sub-bandas (SB1, SB2, SB3, SB4) varia com o tempo. A presente invenção refere-se ainda a um equipamento para a divisão de uma banda de freqüência em sub-bandas, e a um equipamento para transmitir e a um equipamento para receber dados segundo o método de acordo com a presente invenção.
