Abstract

determinados aspectos da presente revelação apresentam um equipamento para comunicação sem fio. o equipamento pode incluir, de maneira geral, um sistema de processamento configurado para gerar um quadro que compreende uma primeira sequência e um conjugado da primeira sequência, e uma interface configurada para dar saída ao quadro para transmissão para um nó sem fio, em que a primeira sequência e o conjugado da primeira sequência são transmitidos simultaneamente por meio de uma primeira e uma segunda cadeia de recepção. a primeira sequência pode ser conhecida pelo nó sem fio antes da transmissão.
