TECHNIQUES FOR ADAPTIVE LIGHT MODULATION IN LIGHT-BASED COMMUNICATION

摘要

Techniques are disclosed for adaptively modulating light in light-based communication (LCom). In accordance with some embodiments, the disclosed techniques can be used, for example, to dynamically adjust light modulation depth based, at least in part, on ambient light levels. In some cases, using the disclosed adaptive light modulation scheme, a given LCom-enabled luminaire (100) may be configured to adjust the modulation depth dynamically and/or control the signal-to-noise ratio (SNR) such that the average light signal is kept constant, regardless of what LCom data is being transmitted. In some cases, the disclosed techniques can be used, for example, to dynamically adjust light modulation depth according to a given minimum light modulation depth assessed by measuring the ambient lighting conditions of the environment of the LCom-enabled luminaire (100). In some instances, an optimized or other target SNR can be provided using the disclosed techniques.
