Performance of PAPR Reduction on OICF with QPSK Modulation

Abstract

The communication network of an electric power system has the important role of conveying information for ensuring a stable supply of electricity. The new techniques for digital transmission have developed to meet the increasing demand for higher data rates in communications which can be used in both wired and wireless environments. To meet out the high spectral efficiency and high data rate, an efficient modulation scheme is to be employed. The Iterative Clipping and Filtering (ICF) is a well-known technique to reduce the peak-to-average power ratio (PAPR) of orthogonal frequency division multiplexing signals. It is more advantageous over other technologies. This Proposed technique shows better performance for reduction in PAPR any technique can be used according to performance. The simulation results show that our proposed power reduction techniques OICF, in this paper, a technique OICF was proposed to reduce the high Peak to Average Power Ratio (PAPR) values. The Simulations are performed using OICF technique with QPSK modulation technique under Additive White Gaussion Noise channel. The simulation result shows the relationship between Complementary Cumulative Distribution Function (CCDF) versus PAPR. The whole simulation is done by a software tool known as MATLAB R2013a
