Recently, orthogonal frequency division multiplexing has been regarded as one of the core technologies for various wireless communication systems. Especially, OFDM has been adopted as a standard for various wireless communication systems such as wireless local area networks, wireless metropolitan area networks, DAB, and DVB. In this paper present PAPR reduction techniques for QAM modulation techniques. The simulation results shown that our proposed power reduction techniques OICF were proposed to reduce the high Peak to Average Power Ratio values. The Simulations are performed using OICF technique with modulation technique under both AWGN channel. The simulation result shows the relationship between Complementary Cumulative Distribution Function versus PAPR.

Conclusion:
In the results shows the original OICF 1st iteration and
Simplified OICF 1st iteration. The performance at the 10-1
clipping probability in simplified OICF,1st iterationthePAPR
4.6dB for N=128, and another simplified OICF, 1st iteration
the PAPR 4.7dB for N=64. In this iteration performance
PAPR reduce by 0.1dB batter at 1st iteration in N=128 for
using 4-PSK.
