摘要：Orthogonal Frequency Division Multiplexing is considered as an advanced communication model which haswide range of applications such as 3G, 4G, and Wi-Fi etc. Though OFDM has lots of advantages over conventionalcommunication models such as FDMA, CDMA still it has some disadvantages in that the major drawback is Peak toAverage Power Ratio. In literature several theories are proposed to resolve this issue but none of the algorithm is designedto meet the practical approach. In our work a novel approach is present to resolve the Peak to Average Ratio byintroducing the variable slopes parameters K1, K2 and inflexion points A (A>0) and CA (0
