Abstract

Un compensador que procesa bloques de datos que incluye una primera trayectoria de procesamiento que procesa una senal para producir senal procesada. Laprimera senal procesada no elimina sustancialmente un fantasma de la senal. Una segunda trayectori a de procesamiento procesa también la senal para producir unasegunda senal procesada. La segunda senal procesada tampoco elimina sustancialmente el fantasma. El sumador suma la primera senal procesada y la segunda senalprocesada para de este modo sus tancialmente eliminar el fantasma.A compensator that processes blocks of data that includes a first processing path that processes a signal to produce processed signal. The first processed signal does not substantially eliminate a ghost from the signal. A second processing path also processes the signal to produce a second processed signal. The second processed signal also does not substantially eliminate the ghost. The adder adds the first processed signal and the second processed signal to thereby eliminate its phantom.
