Abstract
Orthogonal Frequency Division Multiplexing (OFDM) is a digital transmission method is used to increasing higher data rates in communications which can be used in both wired and wireless system. In this paper the issue of the Peak to Average Power Ratio (PAPR) in OFDM which is a major drawback, and presents new and variations to existing algorithms to reduce it. The analysis of the PAPR in OFDM is shown through theoretical analysis and simulation that the occurrence of large peaks in OFDM is actually quite rare [4]. The effect on system performance in terms of the Bit Error Rate (BER) and Power Spectral Density (PSD) is simulated for an OFDM transceiver with a saturated High Power Amplifier. Here in this we will study about OFDM using Complementary cumulative distribution function (CCDF) through MATLAB and analysis of BER using Inter carrier Interference technique (ICI).
