A simple nonlinear companding transform which makes full use of the statistical characteristics of the original multi‐carrier signals and combining them with the simplest clipping theory is proposed to reduce the peak‐to‐average power ratio (PAPR) of multi‐carrier systems. By making a simple truncation to the Rayleigh‐distributed original signals, the proposed scheme not only has low implementation complexity but also outperforms conventional companding schemes.
