On The PAPR Of Binary Reed-Muller OFDM Codes
White Papers This paper presents 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.

Efficient Decoding Algorithms For Generalised Reed- Muller Codes
White Papers Recently a class of generalised Reed-Muller codes has been suggested for use in power-controlled OFDM modulation. Here we present low complexity alternatives which are inspired by the classical Reed decoding algorithm for binary Reed- Muller codes.

Sequences For OFDM And Multi-Code CDMA : Two Problems In Algebraic Coding Theory
White Papers In both cases, the classical Reed- Muller codes turn out to play a critical role. There is an intimate connection between Reed-Muller codes and Golay complementary sequences which can be exploited to produce codes suitable for OFDM.

On Codes With Low Peak-to-Average Power Ratio For Multi-Code CDMA
White Papers The problem of designing such codes is reformulated as a new coding-theoretic problem: codes with low PAPR are ones in which the codewords are far from the first- order Reed-Muller code. Codes which reduce the peak-to-average power (PAPR) in multi...
