Abstract
Long term Evolution (LTE) is a noteworthy undertaking of third Generation Partnership Project, as a move from the third generation (3G) to the fourth generation(4G), has accomplished incredible limit and fast of cellular phone systems without uncertainty. Orthogonal Frequency Division Multiplexing (OFDM) is principal procedure utilized in fourth Generation Long Term Evolution (LTE). Inter Carrier Interference (ICI) and Inter Symbol Interference (ISI) are both problems occur in OFDM due to the loss of subcarrier orthogonality and to defeat this issue utilization of Cyclic Prefixing (CP) is required, which utilizes 20% of available data. usually, OFDM is executed utilizing FFT, then again OFDM can be implemented utilizing orthogonal wavelets. Regardless of the way that are execution of the OFDM structure absolutely a couple inconvenience. One of the genuine drawbacks is the high Peak to Average Power Ratio (PAPR) which realize broad measure of sub-transporters that make controls for possible applications. Partial Transmit Sequence and clipping are some PAPR diminish techniques that have been proposed to defeat this issue
