We present a novel technique which is based on the equalization value where we taken several dynamic ranges from the sin and cosine values and according to those values we first take the lower limit basis on the orthogonal (peak values) and then taken the higher value basis on the orthogonal (peak values). Then apply the rate adaptive method to compare those values according to those changes. We consider those values because the distortion rate is decreases in case of decreasing values in some cases and in some cases increasing values are also important in some cases, so we analyse those cases and then finalize the result based on those parameters. In this paper we show several comparison based on PAPR, Clipped system based on different dynamic values. We also discuss about Randomization
