Abstract

Peak to Average Power Ratio in Long Term Evolution (LTE) system is an challenging and a difficult issue. To avoid the insufficient cyclic prefix, proposed the block size to be minimized, so the bit error rate is decreased to improve the better performance of the system. PAPR reduction is also proposed with two modulation techniques such as Quadrature Amplitude Modulation and Quadrature Phase Shift Keying. In the receiver side, a Maximum Euclidian Distance decoder is introduced to minimize the distance in the Euclidian space to get the output signal. The proposed results of cyclic prefix and peak to average power ratio reduction can be plotted and simulated.
