Abstract

Patente de Invenção: <B>"PROCESSO E DISPOSITIVO PARA A TRANSMISSãO DE DADOS POR MEIO DE UMA INTERFACE DE RáDIO EM UM SISTEMA DE COMUNICAçãO POR RáDIO"<D> A presente invenção refere-se a dois processos e a um dispositivo para a transmissão de dados através de uma interface de rádio, que é organizada em espaços de tempo com blocos de dados finitos segundo um processo de separação de assinantes TDMA (Time Division Multiple Access - acesso múltiplo por divisão de tempo). No primeiro processo, estações de rádio transmitem dentro de um espaço e tempo pelo menos duas das seq³ências de sintonização conhecidas da respectiva estação de rádio receptora, com as quais esta realiza avaliações de canal. As seq³ências de sintonização, no caso, são posicionadas de tal modo no espaço de tempo, que a maior distância de um símbolo de dados da seq³ência de sintonização mais próxima é minimizada. No segundo processo, as estações de rádio transmitem dentro de um espaço de tempo pelo menos uma das seq³ências de sintonização conhecidas da respectiva estação de rádio receptora. Por meio desta e de pelo menos uma outra seq³ência de sintonização conhecida em pelo menos um outro espaço de tempo conjugado a pelo menos uma outra ligação de comunicação, a estação de rádio receptora executa avaliações de canal.
