Abstract

"MéTODO PARA COMUNICAR QUADROS DE DADOS DIGITAIS POR SINAIS MODULADOS EM OFDM, TRANSMISSOR, E RECEPTOR". Método para comunicar quadros de dados digitais por sinais modulados em OFDM , compreendendo primeiros diversos sub-canais portando carga útil e segundos diversos sub-canais portando piloto, por meio do qual quadros consecutivos de dados de carga útil são associados a uma dada configuração de piloto e transmitidos. Antes da transmissão de um quadro de dados de carga útil, cada uma das diversas configurações de piloto é avaliada com relação a PAPR, onde a configuração de piloto sendo associada ao valor de PAPR mais baixo está sendo escolhida para transmissão.
