Iteration correction method is mainly used for ghost canceling algolithm. This method is simple but takes long reduction time. To solve this problem, we have designed a new signal processing. In this processing, the received GCR signal, after noise reduction, can be substituted for the input OCR signal and sent to the transversal filter. By using this processing, we can effectively shorten ghost reduction time. As a result of our experiment, it makes possible to eliminate ghost interference in 2 seconds at an input S/N ratio of 40dB.
