Reduction of peak to mean ratio of multicarriermodulation using cyclic coding

Abstract

A very simple 3/4 rate cyclic code is proposed for the reduction of the peak to average power ratio of multicarrier modulation. The proposed code may be applied for any number of carriers which is a multiple of four. It is shown that the peak to average power ratio can be reduced by more than 3 dB. Numerical computations fully support the result obtained.
