摘要:The principles of Orthogonal Frequency Division Multiplexing (OFDM) modulation have been in existence for several decades. However in recent years the attention towards OFDM has grown rapidly in the field of wireless and wired communication systems because of its advantages. The main problem of OFDM is high Peak to average power ratio (PAPR) which affects the performance and efficiency of high power amplifier used in radio system. In this paper we review and analysis different PAPR reduction techniques. We also describe the comparision between OFDM BER using turbo code and PAPR reduction with different modulation technique using turbo code . In end we made conclusion that turbo code using qpsk technique is better to reduce PAPR and for BER turbo code with half rate is better.
