ACE-PI: Papr reduction in OFDM systems using constellation extension with peak insertion

Abstract

In this study, a proposal is offered in order to calculate the Bit Error Rate with the Signal to Noise Ratio. Here in this paper, it is illustrated that by comparing this analysis among the other mechanisms effective results can be obtained. By applying the ACE scheme in which the clipping technique block is replaced with Peak Inversion (PI) and butter worth band-pass filter is added after the ACE constraint block for generating less distortion and more smoothing. As, it has been concluded from a survey that among different PAPR reduction techniques, PI found to be an effective technique which can reduce PAPR to an extent by incorporating a relatively high impulse. The MATLAB is used for analyzing the enhanced ACE scheme that offers better results in terms of both PAPR and BER.
