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

摘要: OFDM (orthogonal frequency division multiplexing) is a spectrum-efficient digital modulation scheme. It widely used in various applications involving today’s as well next-generation network (NGN). Despite many benefits, it suffers from the drawback of high PAPR (peak-to-average power ratio) transmitted signal. Channel codes are known to reduce (Rajasekhar et al. reduction performance systems using channel coding techniques.
