  Increasing demands on high data rate mobile communications services will
inevitably drive future broadband mobile communication systems toward achieving
data transmission rates in excess of 100 Mbps. One of the promising
technologies which can satisfy this demand on high data rate mobile
communications services is the Orthogonal Frequency Division Multiplexing
(OFDM) transmission technology which falls under the general category of
multicarrier modulation systems. OFDM is a spectrally efficient modulation
technique that can achieve high speed data transmission over multipath fading
channels without the need for powerful equalization techniques. However the
price paid for this high spectral efficiency and less intensive equalization is
low power efficiency. OFDM signals are very sensitive to non-linear effects due
to the high peak-to-average power ratio (PAPR), which leads to the power
inefficiency in the RF section of the transmitter. This paper analyzes the
relation between aperiodic autocorrelation of OFDM symbols and PAPR. The paper
also gives a comparative study of PAPR reduction performance of various channel
coding techniques for the OFDM signals. For our study we have considered
Hamming codes, cyclic codes, convolution codes, Golay and Reed-Muller codes.
The results show that each of the channel coding technique has a different PAPR
reduction performance. Coding technique with the highest value of PAPR
reduction has been identified along with an illustration on PAPR reduction
performances with respect to each code.
