Abstract

Un coprocesador filtro (figura 1) contenido en un Procesador de Señal Digital (DSP) se aprovecha de la naturaleza ortogonal de las señales moduladas durante el proceso de ecualización. Como, tras la recepción, únicamente ciertos valores reales/imaginarios de la señal recibida son útiles para la demodulación, el coprocesador filtro (figura 1) procesa únicamente esos valores para estimar la señal transmitida. Procesando sólo esos valores útiles para la demodulación, el coprocesador filtro (figura 1) es capaz de procesar más información en un intervalo de tiempo dado, realizando un mayor procesamiento en comparación con el arte previo.
