Abstract

USO DE PRIMEIRO E SEGUNDO PREÂMBULOS EM SINAIS DE COMUNICAÇÃO SEM FIO. A presente invenção refere-se a um método e sistema para transmissão de dados dentro de um quadro de sinal. O método compreende a inserção de um primeiro preâmbulo de sincronização em uma primeira localização dentro do quadro de sinal e inserção de um segundo preâmbulo de sincronização em uma segunda localização dentro do quadro de sinal, em que o primeiro preâmbulo de sincronização transmite informação indicativa da segunda localização. O método compreende ainda a emissão do quadro de sinal para um dispositivo de recepção em um ambiente de comunicação sem fio.
