In this paper, we address the peak-to-average power ratio (PAPR) reduction problem of an orthogonal frequency division multiplexing (OFDM) system under error vector magnitude (EVM) and out-of-band emissions (OOBE) constraints. Unlike the existing methods, we first equivalently transform the non-convex objective function—PAPR into the difference between the numerator and denominator, and then analyze its monotonicity of the auxiliary variable. Subsequently, we propose a novel algorithm based on bisection searching to tackle the equivalent PAPR optimization problem. Furthermore, an efficient PAPR reduction algorithm is developed to overcome the challenge of high computational complexity, and a simplified version of this algorithm is provided. Finally, the performance of the proposed algorithms is compared with the state-of-the-art schemes. The simulation results demonstrate the superiority of the proposed algorithms.
