Abstract

In this paper, a new and efficient technique is proposed called Tukey Window Pulse shaping technique for the reduction of PAPR in 4G OFDM system. It is based on proper selection of the time-limited waveforms of different subcarriers. Here, only one IFFT is used in the transmitter side instead of several IFFTs for each subcarrier. So this technique is simpler compared to other methods. The implementation complexity and the cost of the transmitter are significantly low. The PAPR of OFDM system using Tukey Window Technique and Sine Pulse is also compared in this paper.
