Abstract
Un co-procesador de filtro (Fig.1) dentro de un Procesador de Senales Digitales (DSP) aprovecha la naturaleza ortogonal de las senales moduladasdurante el proceso de ecualizacion. Dado que, después de la recepcion, solo ciertos valoresreal es/imaginarios de la senal recibida son utiles para ladesmodulacion, el co/procesador de filtro (fig1) solo procesa esos valores para estimar la senal transmitida. Mediante el procesamiento de solo esos valoresutiles para la desmodulacion, elco-proc esador de filtro (fig.1) puede procesar más informacion en un tiempo dado, produciendo el aumento del procesamientocomparado con el arte previo.
