PAPR reduction of OFDM signals using logarithm based compression functions

The Orthogonal Frequency Division Multiplexing is one of the most efficient techniques used within high speed multicarrier communication systems. An important drawback of these systems is the high peak-to-average power ratio of the transmitted signal. One of the well known solutions to overcome this problem is the signal compression. This paper proposes a new parameterized nonlinear function as an alternative to the existing compression functions. The paper highlights the performances and advantages of the proposed technique through comparison with other standard methods.
