O recorte é um método eficiente e simples que pode reduzir a relação de potência pico-média (PAPR) de sinais de multiplexação por divisão de frequência ortogonal (OFDM). No entanto, o corte causa distorção na banda, conhecida como ruído de corte. Para resolver este problema, um novo esquema iterativo de estimativa e cancelamento (IEC) para ruído de corte é um dos esquemas mais populares porque pode melhorar significativamente o desempenho de sistemas OFDM cortados. No entanto, a IEC explora os símbolos detectados no receptor para estimar o ruído de corte em princípio e os símbolos detectados não são estatísticas suficientes em termos de teoria de estimativa. Neste artigo, propomos a técnica de pós-processamento do IEC, que explora totalmente a estatística suficiente no receptor e, assim, melhora ainda mais o desempenho de um sistema OFDM cortado, conforme verificado por simulações.

Abstract: Clipping is an efficient and simple method that can reduce the peak-to-average power ratio (PAPR) of orthogonal frequency division multiplexing (OFDM) signals. However, clipping causes in-band distortion referred to as clipping noise. To resolve this problem, a novel iterative estimation and cancellation (IEC) scheme for clipping noise is one of the most popular schemes because it can significantly improve the performance of clipped OFDM systems. However, IEC exploits detected symbols at the receiver to estimate the clipping noise in principle and the detected symbols are not the sufficient statistic in terms of estimation theory. In this paper, we propose the post-processing technique of IEC, which fully exploits given sufficient statistic at the receiver and thus further enhances the performance of a clipped OFDM system as verified by simulations.

AB - Clipping is an efficient and simple method that can reduce the peak-to-average power ratio (PAPR) of orthogonal frequency division multiplexing (OFDM) signals. However, clipping causes in-band distortion referred to as clipping noise. To resolve this problem, a novel iterative estimation and cancellation (IEC) scheme for clipping noise is one of the most popular schemes because it can significantly improve the performance of clipped OFDM systems. However, IEC exploits detected symbols at the receiver to estimate the clipping noise in principle and the detected symbols are not the sufficient statistic in terms of estimation theory. In this paper, we propose the post-processing technique of IEC, which fully exploits given sufficient statistic at the receiver and thus further enhances the performance of a clipped OFDM system as verified by simulations.
