“…It allows for high spectral efficiency in channels with limited bandwidth and significantly boosts data rates. OFDM's robustness to both phase noise and time selective channels can be determined by the spacing between its subcarriers [19]. By using multiplexing, data is grouped in packages of M for frequency multiplexing, which is known as OFDM symbol, a different carrying is modulated simultaneously on each data [14].…”

In various areas, wireless systems are used. In order to allocate the available time and frequency resources, these wireless systems require flexible mechanisms. With 5G, transmission rates will be higher, latency will be lower and quality of service and channel capacity will be higher. The physical layer must be able to generate flexible waveforms to meet the above requirements. Currently, Orthogonal Frequency Division Multiplexing (OFDM) transmission does not support 5G communication. In the case of 4G/OFDM, there are many problems in terms of out of band emission, spectral efficiency, and peak to average power ratio (PAPR). An alternative transmission scheme Universal Filtered Multicarrier (UFMC) is introduced to address this problem. The paper compares OFDM with UFMC. The purpose of this paper is to discuss Spectral Density, Spectral Efficiency, Signal to Noise Ratio (SNR) and Bit Error Rate (BER). In comparison to OFDM, UFMC provides better performance.

“…Dalam penelitian ini filter prototipe untuk FBMC dan OFDM dirancang dan hasilnya menunjukkan bahwa FBMC mengungguli OFDM sehingga direkomendasikan pada sistem komunikasi 5G (Kansal & Shankhwar, 2017;Kumar & Gupta, 2015). Selain itu, rekomendasi tersebut juga dikarenakan FBMC dapat menawarkan kapasitas tinggi (Medjahdi et al, 2009).…”

ABSTRAKKebutuhan layanan data pada teknologi 5G sangatlah tinggi. FBMC sebagai solusi dari kelemahan yang ada di OFDM menjadi teknologi yang digunakan pada komunikasi 5G. Pada OFDM, penggunaan ekualisasi sudah sangat banyak dilakukan penelitiannya dan menunjukkan hasil yang bervariasi tergantung dari jenis ekualisasi yang digunakan. Beberapa jenis ekualisasi yang digunakan pada modulasi OFDM antara lain Zero Forcing dan MMSE. Pada penelitian ini, beberapa variasi ekualisasi tersebut diterapkan pada FBMC dan dianalisis perbandingan kinerjanya. Penggunaan modulasi Offset-QAM yang dipadukan dengan FBMC mempunyai fungsi sebagaimana cyclic prefix pada OFDM (CP-OFDM) yakni untuk mengurangi inter symbol interference (ISI). Hasilnya menunjukkan bahwa nilai BER pada FBMC yang menggunakan ekualisasi MMSE pada SNR 5 dB mempunyai nilai sebesar 0,2941 sedangkan BER pada FBMC yang menggunakan ekualisasi ZF sebesar 0,2875. Nilai SER untuk ZF sebesar 0,5514 dan untuk MMSE sebesar 0,5391. Kapasitas kanal Hal ini menunjukkan bahwa kinerja FBMC dengan menggunakan ekualisasi MMSE lebih baik dibanding Zero Forcing.Kata kunci: FBMC, Offset-QAM, ekualisasi, Zero Forcing, MMSE ABSTRACTThe needs of data service on 5G technology is extremely necessary. FBMC as a solution over OFDM's drawbacks becomes the technology that is used in 5G communication. In OFDM technology, various equalisation methods have been used and final result highly depends on which method being used. Some of equalisation methods used in OFDM modulation are Zero Forcing (ZF) and MMSE. In this research, those equalisation methods were used on FBMC modulation and the performances were analyzed. The use of Offset-QAM modulation combined with FBMC actually functioning like Cyclic Prefix on OFDM which is to reduce Inter Symbol Interference (ISI). The result shows that BER value on FBMC that used MMSE equalisation when SNR 5 dB equals to 0.2941 whereas BER value on FBMC that used ZF equals to 0.2875. The value of SER on ZF is 0.5514 and MMSE is 0.5391. Channel Capacity calculation also shows that FBMC performance with MMSE is better than Zero Forcing.Keywords: FBMC, Offset-QAM, equalization, Zero Forcing, MMSE

“…Nowadays, experts predict that combining 5G technologies with Cognitive Radio (CR) would enable communication to be accessed at anytime, anywhere, and by anybody. Furthermore, CR offers a dynamic spectrum-sharing technique that aids mostly in the resolution of the spectrum problem that much of the community is experiencing [20].…”

Fifth Generation (5G) communications are regarded as the cornerstone to household consumer experience improvements and smart manufacturing revolution from the standpoint of industries' objectives. It is anticipated that Envisaged 5G (E5G) mobile technology would be operational in certain developed countries by 2023. The Internet of Things (IoTs) will transform how humans live when combined with smart and integrated sensing devices, such as in-home sensing devices. Recent research is being carried out all over the world to produce a new technique that can be crucial in the success of the anticipated 5G mobile technology. High output, reduced latency, highly reliable, greater scalability, high performance, capacity, bandwidth efficiency, virtual open-air transmission, and efficient energy mobile wireless communications are all being investigated currently. In this work, a comprehensive path for addressing the difficulties and developments associated with 5G mobile technology is provided. The debate and description of a complete analysis of current situations, certain characteristics and prospective scenarios, important technologies, problems and advances, and spectrum allocation of envisioned 5G mobile technologies are provided. Furthermore, this paper analyzes the most notable elements of 5G mobile technology, such as Cognitive Radio (CR), flexibility, accessibility, and cloud-based service offers, which will assure 5G mobile technology's dominance as the main protocol for international communication. Eventually, this paper provides a method for integrating CR with current wireless communication systems, the necessity for further evolution of the E5G network, and the need for comprehensive consideration of architecture evolution and function enhancement to enhance the E5G mobile technologies.
