Abstract
The present invention calculates a difference between present sampling data and sampling data one data unit ahead, cumulatively adds up difference values calculated for every sampling by going back to the time point ahead by the number of samples of a cyclic prefix signal inserted into an initializing signal and confirms the position of the cyclic prefix signal from the sample number for which this cumulative value indicates a minimum value.
