A Novel Approach to Deducing of the Data- PAPR Relation for OFDM System
Journal of Engineering and Sustainable Development, 2012 Orthogonal Frequency Division Multiplexing (OFDM) is a very attractive technique for high-data-rate transmission in wireless and wired applications. The main drawback of the OFDM technique is its high peak to average power ratio (PAPR).
