PAPR Reduction in OFDM systems using Quasi Cyclic LDPC Codes

Orthogonal Frequency Division Multiplexing (OFDM) is a multi carrier modulation technique where the revolution of 4G wireless communication is focused towards OFDM systems. The major drawback of OFDM system is high Peak to average power ratio. The proposed study is based on Peak to Average Power Ratio (PAPR) reduction by the implementation of Quasi Cyclic Low Density Parity Check Codes (QCLDPC). Comparison of PAPR is carried out for LDPC and turbo codes. Simulation results show that the QCLDPC codes give a better reduction of PAPR when compared to LDPC and turbo codes.
