Green and smart buildings (SBs) are promising solutions to the fast-growing and ongoing urbanization around the globe and are the composition of huge services. The SB can acquire a tremendous amount of information and perform proper handling of many broadcasting residents accordingly. With the abrupt increase in the high-quality data transmission demands over long reach for the large number of connected residents in SBs, conventional data transmission techniques are inadequate to provide adequate services. Thus, in this paper, to improve the intelligence and reliability of SBs with high overall efficiency, cost-effectiveness, and security, a hybrid passive optical network (PON) and visible light communication (VLC) indoor broadcasting system is proposed. The bidirectional hybrid PON-VLC consists of integrated time and wavelength division multiplexing (TWDM) and wavelength division multiplexing (WDM) with optical code division multiplexing (OCDMA) PON with red green blue employed light emitting diodes (RGB LEDs) based VLC system. Seven OCDMA codes are utilized in the proposed work at a 10/2.5Gbps per channel transmission rate over hybrid fiber-VLC channels to strengthen the system performance. The simulation results show that the modified new zero cross-correlation (MNZCC) code outperforms other codes and provides a faithful 100km fiber length and 5m VLC range for 200 active residents. Moreover, VLC distance can be incremented up to 10m wireless range by increasing the received aperture diameter of 25cm. Also, the numerical analysis, as well as comparative performance, depicts the superiority of PON-VLC under the impact of impairments and noise in fiber-VLC link-based SBs.

The dimming control is one of the most significant issues to provide both illumination and data transmission for visible light communication (VLC) systems. The receivers-such as variable pulse position modulation (VPPM) receiver-must know the dimming level of the received signal for the demodulation process. To provide a complete solution to this problem, we propose two VPPM receivers that can detect data bits without knowledge of dimming level (KDL). The first one, which is referred to as artificial neural network (ANN)-VPPM, includes the ANN technique to achieve a proper step signal instead of traditional mask signals that are generated by using the perfect KDL. The ANN-VPPM gives a successful bit error rate (BER) performance compared to the unsuitable traditional system (U-TS), which is called the traditional system that decodes the VPPM signal using inappropriate mask signals. If the ANN-VPPM is compared to traditional system (TS), which is the traditional system using a perfect mask signal, the TS has better BER performance than the ANN-VPPM. Hence, the other one that is called the proposed estimation method (PEM) is improved to achieve the same BER performance compared to the TS.An estimation performance is given to indicate the 100% estimation rate and to prove that the BER performance of systems is the same at least signal-to-noise ratio of 22 dB. Additionally, the PEM is saving the optical power of the VPPM signal up to 23% at a BER of 10 −3 when compared to U-TS.

“…[2]. The FSO systems need a direct line-of-sight (LOS) path and their transmission is tremendously controlled by the atmospheric turbulence and the pointing error; hence, these factors affect the performance of FSO systems [3][4][5][6][7]. To combine the benefits of both lines, mixed networks that include both RF and FSO links have been recommended.…”

In this paper, we investigate the outage performance of the three-hop mixed system integrating radio frequency (RF), free space optics (FSO), and under water optical communication (UWOC) system. The closed-form analytical expressions for the outage probability of the system are derived. In the considered system, the RF channel follows the Nakagami-m distribution, the FSO channel observes the Gamma-Gamma fading statistics, and the UWOC link experiences a mixture Exponential Generalized Gamma (EGG) fading distribution. To verify the derived analytical expressions, numerical simulations are also carried out, and we present the influence of the various link parameters such as path loss, atmospheric turbulence, pointing errors, angle-of-arrival fluctuations, water salinity, and scintillation on the performance of the decode and forward (DF) relayed multi-hop communication system.
