“…This condition, however, is not sufficient for F-OFDM and UFMC systems. State-of-the-art (SoTA) UFMC constrains the ZP length and the filter length to be equal to the channel length to trade-off the system overhead and performance [8] [11]. In such a case, the reserved ZP at the transmitter will be occupied by the filter tail completely.…”

“…However, as also pointed out in literature [3] [4] [10] [12], FBMC system is significantly more complex than OFDM-based system. Nevertheless, the proposed interference cancelation schemes are generic and can be combined with other systems such as FC-OFDM and FBMC proposed in [10] and [11], respectively. In this article, we build a framework for multi-service system and categorize the possible subband filtering implementations and synchronized systems in frequency and time domains.…”

“…However, it may result in a higher ISvcBI and a large guard band may be required to reduce interference level in edge subcarriers. In addition, [11] proposed a multi-service system based on the filter-bank multicarrier (FBMC) waveform that may provide a better OoBE and isolation between service bands. However, as also pointed out in literature [3] [4] [10] [12], FBMC system is significantly more complex than OFDM-based system.…”

“…PAPR reduction schemes originated on Active Constellation Extension (ACE), and tone reservation (TR) is presented [7]. The PTS [8], SLM [9], Potencies of trellis-based SLM [10] and Multi-Block Joint Optimization technique [11] are found to be effective in PAPR reduction. However, they require additional processing and often an increased implementation complexity of the system.…”

“…Therefore, it is necessary to reduce it by using a proper reduction scheme at the transmitter. In the literature, there have been several researchers focusing on the PAPR reduction of FBMC/OQAM systems [6][7][8][9][10][11][12][13] [25][26].Active constellation extensions (ACE) with projection onto convex sets (POCS) are used to reduce PAPR in FBMC system but it reduced BER performance [6]. PAPR reduction schemes originated on Active Constellation Extension (ACE), and tone reservation (TR) is presented [7].…”

The filter banks multicarrier with offset quadrature amplitude modulation (FBMC/OQAM) is developing multicarrier modulation technique used in the next wireless communication system (5G). FBMC/OQAM supports high data rate and high band width efficiency. However, one of the major drawbacks of FBMC system is high peak to Average Power Ratio (PAPR) of the transmitted signal, which causes serious degradation in performance of the system. Therefore, it is required to use a proper PAPR scheme at the transmitter to reduce the PAPR. In this paper, a hybrid scheme is investigated with the combination of preceding transform technique and Mu Law Companding technique to reduce PAPR in FBMC systems. Moreover, four preceding techniques are examined to find the best Precoding technique which can be used with Mu law commanding. We assessed the discrete Hartley transform (DHT). The discrete cosine transformed (DCT), the Discrete Sine Transform (DST), and the Walsh Hadamard transforms (WHT) which are applied separately with Mu Companding. The numerical results verify that the FBMC systems with all Precoding technique combined with Mu law commanding can improve PAPR performance of the signals greatly with the best results achieved when the combination scheme consists of the DST Precoding and Mu law commanding for both PAPR and BER performance.

With the start of commercial services using 4th generation cellular systems, we are enjoying full multi-media services using smart phones, and our life style is completely changed from that we had in about 10 years before. Now, we are facing a start point of new era, which is called the 5 th generation systems. Although discussion on designing the 5 th generation systems is not started yet, most of the engineers believe that many revolutional functionality may be supported by the 5G systems compared to the previous generations. Some examples are support of much higher throughput, flexible support of internet of things (IoT), and comfortable control of our social environments.
