Orthogonal Frequency Division Multiplexing (OFDM) could be a digital transmission methodology developed to fulfill the increasing demand for higher information rates in communications which may be utilized in each wired and wireless environments. This paper describes the difficulty of the height to Peak-to-Average Power Ratio (PAPR) in OFDM that could be a major downside, and presents new and variations to existing algorithms to scale back it. The implementation results show that the planned hybrid DCT-SLM technique for reduction of PAPR in OFDM system performs far better than the standalone SLM technique and precoding technique.
