Abstract
Un primer nodo de radio (300) configurado para la multiplexación por división de frecuencia ortogonal (OFDM), que comprende un receptor (310), un transmisor (320), un procesador (330) y una memoria (340) que almacena instrucciones ejecutables por el procesador (330) para causar que el transmisor (320) en un primer modo de operación con una primera separación de subportadora f1: transmita una secuencia de símbolos OFDM prefijados, y en un segundo modo de operación con una segunda separación de subportadora f2: transmita una secuencia de símbolos OFDM prefijados, donde la secuencia de símbolos OFDM transmitidos se alinea con una trama de radio repetida predefinida, que es común para el primer y segundo modos de operación, o con un múltiplo entero de la trama de radio repetida predefinida; y la primera y segunda separación de subportadoras se relacionan con un factor entero, f1 / f2 = p o f1 / f2 = 1 / p, con el número entero p ¹ 1.
