This paper investigates a composite optical receiver for an indoor visible light communication (VLC) system. The optical gain, received power, and signal-to-noise ratio (SNR) are considered to be optimized. However, it is difficult to find a balance between them in general design and optimization. We propose the Taguchi and fuzzy logic combination method to improve multiple performance characteristics effectively in the optical receiver. The simulated results indicate that the designed receiver has the characteristics of an optical gain of 10.57, a half field of view (HFOV) of 45°, a received power of 6.4635 dBm, a signal-to-noise ratio (SNR) of 89.8874 dB, and a spot size of 2 mm. The appropriate weights of the three performance characteristics for the inputs of the fuzzy controllers increase the optical gain by 13.601 dB, and the received power and SNR by 11.097 dB and 0.373 dB, respectively. Therefore, the optical receiver optimally designed by the Taguchi and fuzzy logic methods can significantly meet the requirements of an indoor VLC system.

“…At 50% truncation, a meager reduction in the thermal efficiency of 1% was reported, but the optical efficiency increased because of a lower number of reflections with a reduced reflector length. Li et al 21 demonstrated a reduction in flux non‐uniformity, radiative peak flux on the target surfaces with an increase in concentration ratio by a factor of 4.1, in comparison with the solar collector without the CPC. An enhancement in the thermal efficiency of 27.2% was reported in a solar vacuum tube coupled with the CPC collector than without the CPC, resulting from a higher heat transfer rate between the working fluid and inside wall of the absorber tube 22 .…”

Evacuated tube (ET) solar collectors are utilized in all climatic conditions for harnessing solar energy. This work aims to investigate thermal performance of ET with compound parabolic concentrator collector, integrated to a multiple phase change material-based thermal energy storage (TES) system. The phase change material (PCM) have been selected depending on the degree of stratification in sensible heat storage configuration under constant heat load conditions. The charging experiments have been performed under three different TES configurations viz. sensible heat storage, three ("Case 1") and five ("Case 2") PCMs, using water as the heat transfer augmenting the energy storage by 41% than the sensible heat storage. A higher stratification number in "Case 2" reveals the significance of multiple PCMs in improving the charging efficiency of TES system. Cascaded arrangement of PCMs facilitates the supply of HTF at lower temperature to the collector resulting with an increase in useful heat energy gained. The instantaneous thermal efficiency of collector with "Case 2" is as high as 58%, storing 27 MJ d −1. Use of ET-CPC and TES system with cascaded arrangement of PCMs finds potential application in water heating system.
