BCH/Hamming/Cyclic Coding Techniques: Comparison of PAPR-Reduction Performance in OFDM Systems

OFDM (orthogonal frequency division multiplexing) is a spectrum-efficient digital modulation scheme. It is widely used in various applications involving today’s as well as next-generation network (NGN). Despite many benefits, it suffers from the drawback of high PAPR (peak-to-average power ratio) of the transmitted OFDM signal. Channel codes are known to reduce PAPR (Rajasekhar et al. in PAPR reduction performance in OFDM systems using channel coding techniques. International Conference, IEEE, pp 1–5, 2014; Tsai et al. in IEEE Trans Wireless Commun 7:84–89, 2008; Jiang and Wu in IEEE Trans Broadcast 54:257–268, 2008; Chen and Liang in IEEE Trans Wireless Commun 6:3524–3528, 2007) [1, 2, 3, 4]. In (Rajasekhar et al. in PAPR reduction performance in OFDM systems using channel coding techniques. International Conference, IEEE, pp 1–5, 2014) [1], PAPR-reduction performance of OFDM signal using Hamming and cyclic codes was evaluated and compared. BCH codes are widely used in mobile communication networks (Agrawal and Zeng in Introduction to wireless and mobile systems, 2015; Hazan and Ran in Study of indoor LTE green small-cells using mobile front haul architecture over hybrid fiber-wireless channels, IEEE, pp 185–189, 2016) [5, 6]. Objective of this paper is to evaluate PAPR-reduction performance of BCH-coded OFDM signal and compare the same with the case when Hamming and cyclic codes are used. Simulation results are evaluated using MATLAB® R2015(a). CCDF versus PAPR curves are plotted and used for comparing the performances of the three channel coding schemes.
