$\varepsilon _{\mathbb {X}}$ and the achieved bit error rate (BER) for the uplink positioning and the downlink data transmission, respectively. Results show that the effective area of the photodiode significantly impacts

$\varepsilon _{\mathbb {X}}$

, with smaller areas resulting in higher

$\varepsilon _{\mathbb {X}}$

. It is also observed that the

$\varepsilon _{\mathbb {X}}$

directly relates to the strength of ambient light inducing noise in the system. However, the proposed uplink positioning is less prone to natural ambient light as compared to the traditional downlink visible light positioning. The BER analysis of the downlink data transmission shows that the proposed SVD-based PLS enhances the system’s confidentiality by significantly narrowing the communication zone area by over 90% in comparison to the zero-forcing beamforming scheme and achieves reasonable secrecy capacity.">
