“…Performance of FSO is analyzed [8] using the Equal Gain Combining algorithm and differential chaos shift keying, Binary Phase Shift Keying [9] and Co-OFDM under F distribution model of channel [10]. ITU-R rain attenuation models comparison is widely studied [11][12][13][14] by researchers across the world for different topological regions. The analytic expressions for finding specific rain attenuation parameters k and α are compared with ITU-R values [15] and the relative errors are observed at any frequency in the Terahertz range [16,18].…”

The major obstacle in free space optics FSO is how the data penetrates atmospheric attenuation disturbances like rain, fog, dust storms and snow. The performance of FSO communications is greatly influenced by how one can choose the desired modulation technique. The proposed FSO circuit is designed with a free space range stretching up to 1.85 km. Even though it covers a small radius, we can implement this technique in areas where installing fiber optic cables is impractical. The goal of the proposed work is to use this system to create a new rain attenuation model TSNGH for our region with current rainfall data. For analysis of the FSO circuit under rain attenuation conditions, different kinds of experiments and calculations are carried out with the Optisystem software. With the help of the performance measures; Q factor and BER are evaluated and improved results are accomplished.

Simultaneous illumination and communication using solid-state lighting devices like white light-emitting diode (LED) light sources is gaining popularity. The white light LED comprises a single-colored yellow phosphor excited by the blue LED chip. Therefore, color-quality determining parameters like color-rendering index (CRI), correlated color temperature (CCT), and CIE 1931 chromaticity coordinates of generic white LED sources are poor. This article presents the development of multi-color phosphors excited by a blue LED to improve light quality and bandwidth. A multi-layer stacking of phosphor layers excited by a blue LED led to the quenching of photoluminescence (PL) and showed limited bandwidth. To solve this problem, a lens-free, electrically powered, broadband white light source is designed by mounting multi-color phosphor LEDs in a co-planar ring-topology. The CRI, CCT, and CIE 1931 chromaticity coordinates of the designed lamp (DL) were found to be 90, 5114 K, and (0.33, 0.33), respectively, which is a good quality lamp for indoor lighting. CRI of DL was found to be 16% better than that of white LED (WL). Assessment of visible light communications (VLC) feasibility using the DL includes time interval error (TIE) of data pattern or jitter analysis, eye diagram, signal-to-noise ratio (SNR), fast Fourier transform (FFT), and power spectral density (PSD). DL transmits binary data stream faster than WL due to a reduction in rise time and total jitter by 31% and 39%, respectively. The autocorrelation function displayed a narrow temporal pulse for DL. The DL is beneficial for providing high-quality illumination indoors while minimizing PL quenching. Additionally, it is suitable for indoor VLC applications.
