Abstract
We report experiments of ultraviolet (UV) communication based on
spread-spectrum technique. Field measurements via online UV communication are
conducted to compare the system performances with and without spectrum spreading.
The results indicate that the spread-spectrum technique is capable of suppressing
noise in UV atmospheric scattering channel and therefore improve the system
performance evidently. Details of implementation are also provided to make the
results useful for similar system design in research on optical wireless
communications.
