BER and PAPR Reduction Method for Nonlinearly Amplified OFDM Signals

Abstract

This paper presents a new technique to improve the performance of OFDM systems with nonlinear amplifiers. This method aims to achieve good balances between PAPR and BER at low computer cost. A performance and complexity comparison with known techniques for BER reduction is presented. The results show that the proposed method has lower computational complexity (about 33% fewer multiplications), similar BER performance and better PAPR performance than the other techniques here evaluated.
