Abstract
The invention relates to a method for optimizing the data rate, in a wireless communication system comprising a LED forming an emitting device, and a photodetector forming a receiving device. For a given value of a DC component of the supply signal of the LED, the modulation amplitude of an AC component of this supply signal is adjusted step by step, so as to improve the transmission quality of the signal provided by the LED and received by the photodetector. The invention also relates to an optimization module implementing such a method. Alternatively, the modulation amplitude of the AC component of the supply signal is set, and the value of the DC component is adjusted step by step.
