“…The respective data transmission capability can be reached via the big data concept [69] and developed a smart vehicular communication system that protected vehicular collisions on the roads using LiFi technology. The study in [15] simulated a Direct Current Optical Orthogonal Frequency Division Multiplexing (DCO-OFDM) modulation-based MIMO system used for LiFi technology. In [70], the authors designed a smart traffic system to communicate between automobiles and their traffic environment.…”

“…It is based on the VLC approach, which uses LEDs that are extensively used in houses, workplaces, and road systems to enable highspeed wireless communication. The transmission rates of over 3 Gb/s may be achieved utilizing Orthogonal Frequency Division Multiplexing (OFDM) [15]. However, unlike VLC, where the primary goal is to create a point-to-point link between different devices using visible light, LiFi is a light-based data transmission system that allows for fully interconnected cellular infrastructure, including bi-directional multi-user communication.…”

Due to VLC's restricted transmission range, LiFi leads to further reduced cell size, which raises the size of the service area attocell [15].…”

Visible Light Communications (VLC) are receiving increased attention in the wireless communications research community. VLC is secured, power efficient, and operates in the visible light range, thus RF communication bandwidth limitation is overcome. In this article, the authors enhance the data rate, system complexity, power efficiency, and spectrum efficiency in VLC systems. An innovative unipolar transceiver system is proposed, mathematically analyzed, and compared with other existing techniques and it demonstrates to have a very high data rate ratio (43.75%) with a good system bit energy to noise ratio (𝐸 𝑏 /𝑁 𝑂 ) compared to other existing techniques. Development for the traditional asymmetrically and symmetrically clipping optical (ASCO-OFDM) system is also proposed, which involves combining a modified receiver with the ASCO-OFDM system traditional transmitter. The proposed receiver reduces the system complexity by O (𝑁 log 2 𝑁) with better 𝐸 𝑏 /𝑁 𝑂 than the conventional ASCO-OFDM. Detailed analysis, simulation results, and comparison of the proposed systems with the existing systems are presented beside a brief assessment of existing techniques.
