Abstract

Un método para la operación de un dispositivo de transmisión que se comunica con un dispositivo de recepción es descrito en la presente. El método incluye la etapa del dispositivo de transmisión que selecciona un valor de índice de raíz a partir de un conjunto de valores de índice de raíz. El método además incluye la etapa del dispositivo de transmisión que genera una secuencia de Autocorrelación Cero de Amplitud Constante de dominio de frecuencia en función del valor seleccionado de índice de raíz. El método además incluye la etapa del dispositivo de transmisión que modula la secuencia de Autocorrelación Cero de Amplitud Constante mediante una secuencia de seudorruido. El método además incluye la etapa del dispositivo de transmisión que genera un símbolo de Multiplexión de División de Frecuencia Ortogonal, en donde la secuencia de Autocorrelación Cero de Amplitud Constante de dominio de frecuencia modulada por la secuencia de seudorruido define los valores de subportador para el símbolo de Multiplexión de División de Frecuencia Ortogonal. El método además incluye la etapa del dispositivo de transmisión que transmite el símbolo de Multiplexión de División de Frecuencia Ortogonal como un símbolo inicial de Multiplexión de División de Frecuencia Ortogonal de un preámbulo de un cuadro al dispositivo de recepción.
