“…In [21], the authors unveil the importance of Successive Interference Cancellation (SIC) for NOMA systems, and prove that the SIC decoding order selection schemes are keys to alleviate multiple-access interference. The work [22] focuses on studying a co-existence of multiple 5G services employing OFDM and FBMC waveforms within a resilient photonic millimeter-wave mobile fronthaul architecture. They show, with the application of intra-symbol frequency-domain averaging, that the Error Vector Magnitude (EVM) performance of FBMC is comparable to that of OFDM which traditionally exhibits a better resilience to phase noise.…”

IEEE 802.11p/bd and 3GPP LTE-Vehicular & 5G NR-V2X technologies counteract the doubly-selectivity properties of wireless vehicular communications thanks to the Orthogonal Frequency Division Multiplexing (OFDM). However, this waveform is the source of adjacent channel interference caused by high out-of-band emissions and luck of spectrum access fairness as well as channel capacity limitations. Filter Bank Multiple Carrier (FBMC) and Universal Filtered Multiple Carrier (UFMC) are efficient waveforms reducing the inter-channel interference for 5G physical layer and beyond. This paper provides simulation measurements of the channel capacity under these waveforms by applying the Non-Orthogonal Multiple Access (NOMA) technology with respect to the 3GPP specifications. The results put in evidence less spurious emission and low Bit Error Probability (BEP) using FBMC compared to both OFDM and UFMC waveforms. The spectral efficiency is enhanced as well, thanks to the combination of NOMA with FBMC. The simulation source code is shared for reproduction and further development.

“…Until now, several photonics-assisted ROF systems for multi-band MFH networks have been proposed [4][5][6]. The system in [4] can generate and transmit three vector signals at frequencies of 2.4, 28, and 60 GHz at the same time, which realizes the full band coverage of 5G communication.…”

“…The scheme proposed in [5] can generate and transmit three vector signals at frequencies of 0.7, 1.8, and 26 GHz with improved transmission bandwidth and reduced interferences. To generate millimeter-waves more easily and at a lower cost, optical carriers corresponding to different dense wavelength division multiplexing (DWDM) channels are used to generate millimeter-wave signals [6], and three vector signals at frequencies of 28, 38, and 60 GHz were generated and transmitted simultaneously. However, the existing schemes have not considered how to configure the AAU more flexibly with multi-band microwave signals.…”

A multi-band microwave vector signal generation and transmission scheme is proposed for mobile fronthaul networks based on dense wavelength division multiplexing (DWDM) and optical tandem single-sideband (OTSSB) modulation. At the distributed cell, two adjacent DWDM channels are divided into a group and both the frequency spacing of the adjacent optical carriers and the adjacent DWDM channels are 50 GHz in the system. A pre-distortion circuit is used for mitigating the modulation non-linearity. At an active antenna unit, when both two DWDM channels in a group are selected, six vector signals centered at different frequencies from 3.5 to 60 GHz are generated. When only one of the DWDM channels is selected, two vector signals centered at 16.5 and 33 GHz or two vector signals centered at 3.5 and 10 GHz can be generated. A simulation is performed to verify the proposed system and its performance by employing 16 quadrature amplitude modulation signals. In the simulation, the error vector magnitudes (EVMs) for different frequency vector signals are around 1% in the back-to-back case. When a section of 25-km single-mode fiber is inserted, the EVMs are still better than 5%.

“…In [15], although UFMC-RoF was converged with a standard PON based on a single carrier 4-PAM signal, it is of more interest to investigate UFMC performance in terms of the convergence with the wired PON signals based on multicarrier waveforms such as that employed in an OFDM-PON. This situation is created because the intermixing between the two waveforms (UFMC and OFDM) will affect the performance of the integrated network [14,16]. In addition, it is important to implement the multiple-input multiple-output (MIMO) technique in the millimeter-wave band for next generation-PON as it will be used for fronthauling the future 5G systems [17], which provides improved system reliability [18,19].…”

Next generation integrated fiber-wireless access networks will require low-cost and high capacity deployment to meet the customer demand. A new configuration of radio over fiber-passive optical network (RoF-PON) architecture, including two 60 GHz multiple-input multiple-output (MIMO) based on a 5G universal filtered multicarrier (UFMC) waveform and wired signal utilizing orthogonal frequency division multiplexing (OFDM), is described. At the optical line terminal MIMO signals are integrated as upper and lower sidebands of the wired OFDM signal. This integration approach employing single sideband frequency translation (SSB-FT) reduces the complexity of the transceiver design and provides high spectral efficiency because the two MIMO-RoF and wired signals transmit at the same frequency. Improved techniques are also employed to upconvert and downconvert the 60 GHz millimeter wave (MMW) being remote optical heterodyning and self-heterodyne, respectively. The MIMO-RoF signals are therefore transmitted at low frequency over the standard single mode fiber to avoid the impairments induced at higher frequencies and the remote optical local oscillator is reused to downconvert the two 60 GHz MMWs producing a costeffective system. Simulation results demonstrate very satisfactory network performance when using a downstream link over a 20 km span standard-PON.
