“…However, this method limits the number of MIMO streams per wavelength to only two. Among these methods, the most used and proven to be successful are: PDM [6,40,[50][51][52][53][54][55][56][57][58][59][60], using comb techniques to generate multiple wavelengths [49,[61][62][63][64] and also hybrid method between them as shown in Figure 8c [6]. It takes benefit from the optical frequency comb techniques and high bandwidth optical modulators (up to 100 GHz) as shown in Figure 8b [64][65][66][67], and multiple widely separated wavelengths can be produced from one continuous-wave (CW) laser.…”

Next-generation access/mobile networks have set high standards in terms of providing wireless services at high data rates in order to keep up with the vast demands for other mobility and multiple services. Wireless-optical broadband access network (WOBAN) technology, also known as fibre-wireless (FiWi), has uncovered incredible opportunities for the future of next-generation networks because it gets the best of both domains: huge bandwidth provided by the optical fibre and high ubiquity of the wireless domain. The objective of FiWi networks is to integrate the high data rate and long reach provided by optical networks and the ubiquity and mobility of wireless networks, with the target to decrease their expense and complexity. Multiple-input–multiple-output (MIMO) is an inevitable technique for most of the new mobile/wireless networks that are driven by the huge data rates required by today’s users. Consequently, to construct any FiWi system for next-generation (NG) access/broadband networks, an MIMO technique has to be considered. This article presents a comprehensive, contemporary review of the latest subsystems, architectures and integrated technologies of MIMO wireless signals backhauling using optical fibre or fibre access networks, such as passive optical networks (PONs). An overview for FiWi, PONs and MIMO wireless systems is provided. In addition, advanced techniques of accommodating the MIMO wireless signals over optical fibre are explained and compared. Different types of wireless MIMO signals over fibre, such as 5G, WiFi and related transport technologies, are reviewed. Moreover, future research trends are also discussed.

“…The straightforward solution to transport independent MIMO signals is to use as many optical links as there are MIMO channels, which leads to an increase in deployment costs. Several works have dealt with this challenge by using different multiplexing schemes to transport mmWave MIMO signals over a single optical link, including Wavelength Division Multiplexing (WDM) [17], Polarization Division Multiplexing (PDM) [18] and Optical Subcarriers Multiplexing (OSCM) [19].…”

“…The complexity of this scheme increases by increasing the number of antennas in the MIMO system. In [18], a PDM scheme has been proposed to transport a 2x2 MIMO signal at 60 GHz, where a dual tone laser source is used to feed two independent Dual-Drive Mach-Zehnder Modulators (DD-MZMs). In addition, two LOs are implemented to perform frequency translation of OFDM signals.…”

“…The photonic generation of mm-wave signals is one of the basic mechanisms in RoF systems. Nowadays, there are many proposed approaches for the photonic generation of mm-wave signals, among them are direct intensity modulation [3], optical external modulation [4], [5] optical heterodyne [6], and optical mode-locked of the two laser diodes [7]. Optical external modulation has many advantages such as good stability, wide tunability range, and high conversion efficiency; therefore, it is considered the most significant one among the above approaches.…”

In this paper, a cloud-radio access networks based (C-RANs) radio-over-fiber (RoF) system have been reported with the optical generation of 28 GHz and 57 GHz millimeter-wave using phase modulation and stimulated Brillouin scattering effect in optical fibers. As a result, a cost-effective system with improved performance is achieved by the proposed method. Based on the proposed scheme, a 28 GHz (licensed band) and 57 GHz (Un-licensed band) optical millimeter-waves are generated by simulation only using 14 GHz and 16 GHz radio frequency (RF) respectively. Because the performance of any optical transmission system is limited by the Q factor and the bit error rate (BER) and any input power of the laser into the fiber needs to be less than the Brillouin threshold in order to avoid the sharp degradation of the Q factor. Also, the Brillouin threshold for this study setup is determined which is around 6 dBm in the case of licensed band and 2 dBm in the case of unlicensed band. The simulation results show that the proposed scheme can provide 100 km single-mode fiber for 28 GHz and 25 km for 57 GHz with transmission rates of 10 Gbps for both of them. In addition, a stable millimeter-wave RoF link, high quality carriers, and a reduction in nonlinearity effects are achieved with the proposed scheme.
