A Survey on PAPR Reduction Methods for OFDM System
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 1
Abstract
Orthogonal Frequency Division Multiplexing (OFDM) which falls under the multi carrier modulation category. OFDM has gain popularity in number of applications in wireless networks. A very desirable factor in most application is high data rate. Even though OFDM is used as a standard all over the world in order to provide users with high data rates followed by advanced intensive applications wirelessly, bit it faces various challenges like Peak to Average Power Ratio(PAPR), The PAPR problem in OFDM signal can be considered as a big drawback in the high data rate and bit transmission in the signal due to its unstable spikes and behavior. There are various techniques to overcome the problem of PAPR like Partial Transmit Sequence, Selective Level Mapping, Block Coding, Clipping and Filtering, Tone Injection. In this paper several techniques have been discussed for PAPR reduction.
