摘要：Wireless communications have been developed widely and rapidly in the modern world especially during the last decade. Orthogonal Frequency Division Multiplexing (OFDM) has grown to a popular communication technique for high speed communication. Besides of the advantages, one of main disadvantage of OFDM is high peak to average power ratio (PAPR). In this paper, a PAPR reduction method is proposed that is based on combining clipping with Walsh Hadamard Transform (WHT).WHT is a precoding technique which is having less complexity compared to the other existing power reduction techniques and also it can reduce PAPR considerably and results in no distortion. The performance of the proposed scheme is examined through computer simulations and it is found that power reductions are obtained
