10 pagesDate: March 17, 2022


For Wireless broadband communications, Orthogonal Frequency Division Multiplexing (OFDM) is a frequently used method. However, OFDM systems have some disadvantages. The problem of high Peak-to-Average Power Ratio (PAPR) is one of the most serious restrictions. Some linear components, such as power amplifiers have distortions. A variety of methods have been used for the mitigation of PAPR in OFDM Signals. Among these methods, Clipping-based approaches have been developed for effective PAPR decrease and ease of deployment. The PAPR of OFDM Signals is reduced using a uniform distribution approach (UD) proposed in this paper. The proposed approach introduces three distinct approaches, each of which enables PAPR mitigation through Iterative Clipping and Filtering (ICF) without relying on clipping ratio (CR). We discovered that our method minimizes the PAPR of OFDM Signals much better than the traditional clipping and filtering techniques.
