Abstract :
|
Orthogonal Frequency Division Multiplexing is a multi-carrier system. In this a single carrier is divided into number of sub- carriers. These subcarriers are orthogonal to each other, this helps to reduce ISI effect and full bandwidth is utilized. OFDM is of great interest by researchers and research laboratories all over the world because it gives high data rate. One of the major problems observed in OFDM system is PAPR (Peak to Average Power Ratio).This PAPR must be Reduce for efficient transmission. Different techniques can be used for reduce PAPR in OFDM system. In this Paper we describe all techniques which can be used to reduce PAPR in OFDM system. All the techniques perform best in reduction. This paper contains an overview of all techniques to reduce PAPR in OFDM system.
