Abstract
Se provee un método para ecualizar vectores de símbolo OFDM recibidos en una senal de radio en canal en banda AM, que incluye un portador principal y un primer y segundo sub-portadores modulado BPSK. El método comprende los pasos de: computar una senal de magnitud BPSK; filtrar la senal de magnitud BPSK; filtrar las muestras complejas recibidas en el portador principal; usar la senal de magnitud BPSK filtrada y las muestras complejas filtradas recibidas en el portador principal para computar una pluralidad de coeficientes de ecualizacion de desvanecimiento planos; y multiplicar los vectores de símbolo OFDM por lo coeficientes de ecualizacion de desvanecimiento plano. También se provee un receptor que incluye un ecualizador, el cual opera de acuerdo con el método.
