Visible light communication (VLC) technology has arisen as promising candidate to solve the critical challenges of wireless communication networks. In particular, the evolving explosion in use of internet services requiring high bandwidth will soon become a great potential problem among the service provider. Meanwhile, this paper describes a physical layer solution to provide data transmission in the VLC networks. In the paper, it is aim to examine the performance comparison of SC-PPM (Subcarrier Pulse Position Modulation) demodulator schemes. It is considered three receiver techniques to assemble the demodulator techniques to SC-PPM receiver system. Firstly, the traditional PPM (T-PPM) demodulator has been applied on the SC-4PPM receiver system to estimate the slot that includes high frequency signal that is referred to as subcarrier signal. To successfully detect the bits by using traditional PPM receiver, it must be known the dimming level of received SC-4PPM signal. This is a serious problem to ensure data transmission in the real-time VLC systems due to challenge of providing the variable dimming level knowledge at the receiver side. In another receiver model that is referred to as PD (Peak Detector), it is aim to detect peak values of slot with high frequency signal. The disadvantage of this system is that BER (Bit Error Rate) performance depends the difference between peak and bottom values of subcarrier filled slot. Hence, second method is improved to achieve the similar BER performance at all dimming levels between 12.5% and 87.5%. This receiver model is called as IPD in the paper

“…In VLC first hop, a small BER is noticed, in the second hop, the error increased due to the repeater amplify and forward scheme errors, while at higher hops have higher max errors. In contrast, RF communication has near-constant BER at distances from 100 m (i.e., after the VLC hop maximum communication distance) up to 200 m. We consider no communication at distances greater than 200 m to ensure the minimized interference in RF (omnidirectional radiation pattern) and to maximize the frequency reuse in car-to-car RF communication Okasha et al J Wireless Com Network (2022) 2022 Eq. ( 5), we add or remove the transfer function H of each weather condition to study its effect.…”

“…( 5), we add or remove the transfer function of each weather condition to study its effect. In clear weather (i.e., only the line-of-sight transfer function is considered), the pure VLC channel communication data rate is about three times that of the pure RF channel communication data rate Okasha et al J Wireless Com Network (2022) 2022 In heavy fog (i.e., both the line-of-sight transfer function and fog effect transfer function are considered), the pure VLC channel communication data rate of 206 Mbit/s amounts to about twice that of pure RF communication 98 Mbit/s. In heavy rain (i.e., both the line-of-sight transfer function and rain effect transfer function are considered), the pure VLC channel communication data rate of 257 Mbit/s is five times that of the pure RF channel communication with 48 Mbit/s.…”

This paper combines the advantages of both VLC communication and RF communication for car-to-car applications to achieve a higher data rate, more range coverage, smaller delay, and smaller BER. In the proposed scheme, the VLC maximum communication distance is chosen as 100 m per-hop approximately, which can be extended through multi-hop up to the timeout window of 5 hops. In contrast, the RF maximum communication distance is chosen as 200 m per-hop approximately, which is reasonable at the frequency band of 70 GHz to 90 GHz due to the high attenuation at this frequency band. A MATLAB simulation for a car-to-car framework is built to demonstrate and compare the BER, throughput, and delay outcomes at a hybrid VLC and RF communication. Our results show that VLC can achieve up to four times of the RF throughput while maintaining low BER of 10−6 and small delay of 10−4 with respect to RF communication only.

“…The camera detector used in OCC is a low frame rate that needs special modulation schemes to avoid ickering illumination (Catualin Beguni, 2023). OCC technology is described within the IEEE 2018 standard of 802.15.7 (Mishra, 2022). The IEEE 2018 standard of 802.15.7 physical layer (PHY) for OCC contains three categories within it such as:…”

This paper combines the advantages of both cognitive radio (CR) communication and visible light communication (VLC) for car-to-car applications to achieve a higher data rate, low delay, minimum outage probability, minimum cost, and minimum bit error rate (BER). CR technology hops among the existing radio frequency (RF) available channels to increase the RF spectrum usage efficiency and dodge the scarcity limitation. Moreover, using CR as a license-free application will reduce car-to-car communication costs. However, CRs require a common control channel (CCC) to communicate the spectrum availability map within the CR network and to inform the receiver end about the change in the transmitter-end channel. Therefore, the CCC is the bottleneck in the car-to-car CR network. Therefore, we explore the types of CCCs and use each of them to solve this bottleneck issue. In the proposed scheme, we assume alternative CCCs such as licensed overlay, unlicensed CR overlay in the ISM band, underlay CR, and using VLC. A MATLAB simulation for a car-to-car framework is built to demonstrate and compare these types of CCC through the chosen metrics. Our metrics include data rate, delay, outage probability, cost, and bit error rate. The comparison analyses shall include comparing VLC versus the other CCC types. We compare practical systems, not the theoretically achievable system therefore the results might prefer a CCC type according to one metric and prefer another type of CCC due to the second metric. Our results show that VLC can achieve up to 90% of the licensed data rate with a small outage probability of 21.2% while maintaining moderate BER and delay. In addition, VLC presents the minimum cost, and as the introduced combined metric it placed second after the licensed type with a score of 84.2%. In conclusion, with the VLC’s bright future of expansion and growing the car-to-car application, we have proven VLC is worthy of implementation practically in modern cars.
