On the PAPR of binary Reed-Muller OFDM codes

Abstract

We present a lower bound on the peak to average power ratio (PAPR) for the second order cosets of binary Reed-Muller code by classifying the codewords using their Walsh Hadamard transform (WHT) vectors. This result categorizes the second order cosets of binary Reed-Muller code as per their PAPR by observing their WHT spectrum.
