Abstract
Se describe un método en un circuito transmisor (200) de generación de una señal que comprende una primera secuencia de símbolos de OFDM, que se va a transmitir dentro de una banda de sub-frecuencia de una segunda secuencia de símbolos OFDM. Un primer CP de la segunda secuencia de símbolos OFDM tiene una primera duración, y un segundo CP de la segunda secuencia de símbolos OFDM tiene una segunda duración. Con el fin de generar tanto el primero como el segundo prefijos cíclicos con un número entero de muestras equidistantes, se requiere un primer régimen de muestreo. El método comprende generar (100) la señal que comprende la primera secuencia de símbolos OFDM a un segundo régimen de muestreo, inferior al primer régimen de muestreo, y que ajusta (110) una fase de muestreo durante CP.
