Abstract

One of the potential technologies for a future wireless network is filtered-OFDM (F-OFDM). The capacity to handle numerous asynchronous sub-band transmissions is necessary in order to accommodate the diversity of services. However, multicarrier transmission systems with multiple subcarriers transmit signals with high Peak-to-Average Power Ratios (PAPR). The high PAPR value, which results in performance degradation and high-power consumption as a consequence of various distortions, therefore constitutes a significant challenge with the F-OFDM system. In order to obtain improved PAPR reduction, the Cluster Scrambling Codeword (CSC) method and its hybrid precoding approach are developed in this paper, which aims to add to this expanding field of research. This novel concept of the bit-data sequence shifting approach can reduce PAPR more effectively than the traditional scheme. In comparison with the conventional F-OFDM system, the simulation results indicate that the hybrid codeword shifting methodology, CSC+CVMT, achieves a 53.84% PAPR improvement at 4.2dB.
