AbstractIn this paper, two major attractive effective reduction strategies, the tone cancellation and clipping technique, we propose to combined to reduce peak-to-average (PAPR) in OFDM. We propose that tone cancellation and clipping technique for reducing the PAPR, PTS performs better than other conventional methods. We review prior work from [11,12] with analytical results showing that the proposed schemes can achieve significant reduction in computational complexity while keeping good PAPR reduction. Results of simulations show almost the same PAPR reduction performance as compared with the genetic algorithm-based TR method which has been known to have the best performance and obtains using the tone cancellation through clipping technique for reducing the PAPR. This motivates us to combine these two methods as they address independent features and we can expect a combined method would be better that either one.
