“…Although there are already studies and proposals in this field of interest [2], the coexistence between RF and OWC is still an open research area [3], [4], but it is not the focus of this paper. Moreover, although consumer optical communications are mostly guided [5], the number of wireless applications for it is growing in recent years [6], [7], mainly for the following advantages that make OWC an appropriate candidate to complement RF communications:…”

In this paper, a novel cooperative transmission and reception scheme in Visible Light Communications (VLC) is proposed and evaluated. This new scheme provides improvements and reliability in large indoor scenarios, such as corridors, laboratories, shops or conference rooms, where the coverage needs to be obtained by using different access points when VLC is used. The main idea behind the proposal is a simple cooperative transmission scheme where the receiver terminal will obtain the signal from different access points at the same time. This proposal outperforms traditional VLC schemes, especially in Non-Line-of-Sight reception where around 3 dB of gain with respect to the traditional schemes can be obtained for unoptimized parameters and larger than 3 dB could be easily achieved. The cooperation is studied in terms of the percentage of light coming from the main access point and a parameter called sidelobes' amplitude level. The performance is evaluated according to the location into the atto-cell 1 .
