Peak to Average Power Ratio reduction method for Orthogonal Frequency Division Multiplexing in 4G Communication

Recent development in data communication applications, the role of Orthogonal Frequency Division Multiplexing (FDM) technology is unavoidable. The OFDM system improves the multipath fading channel and bandwidth in effective manner. But the main problem in OFDM is large fluctuations. This often affected the design performance and produces the poor results when compared to the existing methodologies. The development and redesign of the existing system contains high power amplifiers, signal analyzer and device modules. All these devices should have the linear dynamic in range. The above devices are not functioning properly the huge data loss may occur and it will be affected the data transmission and it produces the interference in signals and inter modulation distortions. Hence, the overall power performance of the system is very poor and it makes the system in unconditional. In this paper we discussed Peak to Average Power Reduction (PAPR) techniques with HPA (High Power Amplifier) for improvement of overall response of the system.
