BER analysis to mitigate PAPR in a turbo coded OFDM System
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 10
Abstract
This The peak to average power ratio (PAPR) of a transmitted signal is one of the main bottleneck problem in wideband multi-carrier systems that uses orthogonal frequency division multiplexing (OFDM) technique and mitigating the effects of PAPR on such system is critical. In this paper, different techniques to reduce PAPR are reviewed and analyzed. Also the Bit error rate is analyzed for an OFDM system by adding turbo codes which is one of the popularly used forward error correction code (FEC) along with PAPR reduction techniques. Simulation is done considering the additive white Gaussian noise (AWGN) and Rayleigh channels. Simulation results show the improvement in system throughput and error rate by using the PAPR reduction techniques in concatenation with a turbo coding.
