This paper presents four novel techniques for peak-to-average power ratio (PAPR) reduction in filter bank multicarrier (FBMC) modulation systems. The approach extends on current PAPR reduction active constellation extension (ACE) methods, as used in orthogonal frequency division multiplexing (OFDM), to an FBMC implementation as the main

High peak-to-average power ratio of the transmit signal is a major drawback of multicarrier transmission such as OFDM. This paper describes Orthogonal Frequency Division Multiplexing (OFDM) system with Continuous Phase Modulation (CPM) mappers is considered. Such a system is known to provide superior bit error rate performance by virtue of the memory introduced by the CPM mapper compared to OFD...

One of the major drawbacks of adding signal techniques of reducing peak to average power ratio (PAPR) is the variation of the average power of the transmit signal that undoubtedly degrades the performance of transmission. In this paper, assuming that the baseband OFDM signal is characterized as a complex Gaussian process, we derive an approximation by a simple closed form of the variation of th...

Orthogonal Frequency Division Multiplexing (OFDM) is a very effective field of research of wireless communication and also the high speed data transmission process in this system. The main drawback of OFDM system is high Peak to – Average Power Ratio (PAPR). Due to high PAPR there is inefficient use of high power amplifier and this could limit transmission efficiency. Selected mapping (SLM) is ...
