摘要

Visible light communications (VLC) is a promising technology that is regarded as a promising alternative to radio frequency (RF), due to its unregulated free bandwidth, considerable life expectancy, low cost, and efficiency. In this paper, an optical attocells configuration model is proposed. It incorporates a low number of LED chips for power efficiency. It is evaluated in terms of its data rate and BER performance. Also, it is optimized to achieve higher received power and SNR distribution. This was achieved by varying its field of view (FOV). Besides, various data rates were implemented to evaluate its performance. A data rate of 100 Gb/s was achievable with acceptable BER. Moreover, alternative modulation techniques were implemented to investigate the system performance. Further, they included NRZ-OOK, RZ-OOK, BPSK QPSK DPSK, and L-PPM. 4-PPM had achieved the best BER performance.
