CLASSICAL CLIPPING: A FUTURE PROSPECTIVE TO REDUCE THE PAPR IN OFDM SYSTEM

Orthogonal Frequency Division Multiplexing (OFDM) is a multicarrier transmission technique that becomes the best choice in wireless high-data-rate transmission. The drawbacks of OFDM are high Peak-to-Average Power Ratio (PAPR) and sensitivity to frequency offset. High PAPR Decreases the amplifier’s efficiency. The simplest PAPR reduction method is clipping, but it gives in-band and out-of-band distortion that degrades the performance of the system. There are Various types of clipping, such as classical clipping, deep clipping, and smooth clipping. The Classical Clipping method is focused in this paper for reduction of PAPR using different modulation techniques. Through the Analysis, it is shown that Clipping using QPSK is better than BPSK.
