Multi-carrier communication systems are facing a significant trouble in reality. Multi-Carrier Code Division Multiple Access and Orthogonal Frequency Division Multiplexing be the pattern of multi-carrier modulation systems. The difficulty in veracity is owing to the existence of huge quantity of sub-carriers. As a result, it outcome with high Peak-to-Average Power Ratio which introduce solemn disturbances for instance lower resolution and reduction in battery life. Thus it is essential to diminish this high Peak to Average Power Ratio. Reduction in PAPR have showed the way of consuming less power, low Bit Error Rate, improvement in spectral bandwidth, lesser amount of complexity and cost. In this paper, different PAPR reduction techniques were investigated and in addition the principles for choosing the PAPR reduction technique were also analyzed.
