This paper proposes a new architecture for outdoor low data rate visible light communication applications. Considering the performances of the digital filtering, the proposed architecture considers the usage of digital signal processing (DSP) as an alternative to the analog signal treatment. The key aspects related with the implementation of the VLC receiver are discussed and motivated through simulations...
This paper presents the investigation results concerning the negative effects of noise on the data signal in the case of Visible Light Communications (VLC). The motivation of this work was to offer a better understanding of the modifications of the data pulse in the presence of noise. Better understanding of the noise effect on the pulse width can help mitigate it and improve the communication performances...
This paper approaches the issues concerning the usage of the delay modulation as a coding technique used for outdoor Visible Light Communications (VLC) under PHY I layer of the IEEE 802.15.7 standard. We perform a comparative analysis between the Manchester code, as a traditional code, specified by the upper mentioned standard and the Miller code as a possible candidate for outdoor MIMO applications...
