Abstract
Un método para transmitir información digital que comprende las etapas de corrección de errores hacia delante, de una pluralidad de bits de información digital usando códigos convolucionales complementarios mapeados en trama, modulando una pluralidad de senales portadoras con los bits de errores hacia delante corregidos y transmitiendo las senales portadoras. La modulación puede incluir la modulación por amplitud independiente de componentes en-fase y cuadratura de la constelación QAM usando puntos de constelación de código Gray correspondiente a niveles de amplitud. Los transmisores que transmiten senales de acuerdo con el método y receptores que reciben tales senales, también están incluidos.
