Abstract

Las realizaciones utilizan símbolos OFDM para comunicar ID de la red. Los IDs están codificados en símbolos que utilizan los IDs de la red como semillas para mezclar pilotos respectivos que son entonces transmitidos al utilizar los símbolos. Los pilotos pueden estar estructurados en un unico símbolo OFDM.y/o multiples símbolos OFDM. La estructura de símbolo unico para transmitir los Ids de la red es independiente del numero de bits de ID de la red y minimiza el desalineado de frecuencia y los efectos Doppler. La estructura de símbolo multiple permite emplear una exactitud de tiempo más grosera a expensas de transmitir símbolos adicionales. Muchas realizaciones emplean una funcion de busqueda para encontrar posibles candidatos de ID de la red de un símbolo transmitido y una funcion de seleccion para encontrar un candidato optimo de una lista de candidatos de ID de la red.
