Abstract: The Transmission of signals from one end to other end without intrusions and efficient manner is most hilarious task. Accordingly, OFDM method is utilized for transmission which has better resistance against the multipath fading and yields better efficiency among other wireless communication processes. Even though bounded with more advantages PAPR problem is undesirable for OFDM which in turn readily reduces the data rate. Hence, PAPR Problem reduction improves the quality of service. Thus the reduction of PAPR is done by utilizing adaptive clipping and windowing methods with interdependent discretization approach by utilizing CAIM algorithm, which arrange signal in equal discrete level and makes clipping with reduced BER and Planck-tapper window further yields renovated signal with amplitude varied linear signal which in turn mitigates the PAPR and also allows the signal to flow on exact discrete interval which readily improves the efficiency to a great extent. This proposed methodology is implemented in MATLAB software.
