Abstract	3rd Generation Partnership Project Long Term Evolution (3GPP LTE) has adopted orthogonal frequency division multiple access (OFDMA) as downlink and single carrier frequency division multiple access (SC-FDMA) as uplink for multiple access scheme. SC-FDMA is adopted in uplink due to its low peak to average power ratio (PAPR). To reduce PAPR in OFDMA, several techniques are used in literature. SC-FDMA is adopted in 3GPP as it shows better PAPR characteristics than OFDMA. Many researches are still going on to find the impact of different parameters on PAPR in SC-FDMA. In this paper, a PAPR reduction technique is proposed where the precoding is done in the first step and at the second step, clipping is performed using SC-FDMA environment. Result shows that the PAPR is reduced at the increase in number of clips.
