“…Thus, high-power amplifiers must be operated at the transmitter. The FBMC system uses an OFDM-based PAPR reduction approach, such as absolute exponential companding, logarithmic rooting, tangent rooting, the A-law, and rooting [100], [101]. The objective outlined in [76], [100], [101] is to reduce the PAPR issue.…”

The fifth-generation (5G) wireless communications have been deployed in many countries with the following features: wireless networks at 20 Gbps as peak data rate, a latency of 1 ms, reliability of 99.999%, maximum mobility of 500 km/h, a bandwidth of 1 GHz, and a capacity of 10 6 up to Mbps/m 2 . Nonetheless, the rapid growth of applications, such as extended/virtual reality (XR/VR), online gaming, telemedicine, cloud computing, smart cities, the Internet of Everything (IoE), and others, demand lower latency, higher data rates, ubiquitous coverage, and better reliability. These higher requirements are the main problems that have challenged 5G while concurrently encouraging researchers and practitioners to introduce viable solutions. In this review paper, the sixth-generation (6G) technology could solve the 5G limitations, achieve higher requirements, and support future applications. The integration of multiple access techniques, terahertz (THz), visible light communications (VLC), ultra-massive multiple-input multiple-output (um-MIMO), hybrid networks, cell-free massive MIMO, and artificial intelligence (AI)/machine learning (ML) have been proposed for 6G. The main contributions of this paper are a comprehensive review of the 6G vision, KPIs (key performance indicators), and advanced potential technologies proposed with operation principles. Besides, this paper reviewed multiple access and modulation techniques, concentrating on Filter-Bank Multicarrier (FBMC) as a potential technology for 6G. This paper ends by discussing potential applications with challenges and lessons identified from prior studies to pave the path for future research.

“…In [22], PAPR reduction gain is achieved using non-linear companding schemes such as μ-law companding with μ = 5, A-law companding with A=5, rooting companding with R=0.4, tangent rooting companding with L=5 and R=0.4, and logarithmic rooting companding with L=5 and R=0.4 in FBMC-OQAM system but at the same time, BER performance of the system deteriorates with the use of companding techniques as shown in figure 6. This is because of the channel noise amplification by the inverse companding performed at the receiver.…”

“…In [22], PAPR reduction gain is achieved with the use of companding techniques but at the cost of reduced BER performance as compared to that of conventional FBMC-OQAM system without any companding. In this paper, we aim to combine channel coding techniques such as convolutional codes, and turbo codes with a nonlinearly companded FBMC-OQAM system to provide better BER performance along with PAPR reduction gain when compared to a conventional FBMC-OQAM system.…”

Filter Bank Multicarrier with offset QAM (OQAM) is a suitable multicarrier waveform technique for 5G and future wireless networks and standards. Being a multicarrier technique, it suffers from high peak-to-average-power ratio (PAPR) problem. In this paper we have used some non-linear companding transforms such as μ-law, A-law, rooting, tangent rooting, and logarithmic rooting to overcome the PAPR problem. Since non-linear companding techniques degrade bit-error-rate (BER) performance of a system. Hence, some channel coding techniques such as convolutional codes and turbo codes are employed to enhance the BER performance of non-linearly companded FBMC-OQAM system. It was observed that the combination of convolutional coding with logarithmic rooting companding provides PAPR reduction gain of about 4.896 dB and coding gain of about 2 dB as compared to conventional FBMC-OQAM system and is an appropriate choice for applications requiring reduced system complexity. It was observed that the combination of turbo coding with logarithmic rooting companding provides PAPR reduction gain of about 4.922 dB and a sufficiently high coding gain of about 7 dB as compared to conventional FBMC-OQAM system and is suitable for applications requiring improved data reliability at the expense of increased system complexity and latency.
