10 Gb/s two-dimensional free-space optical code division multiple access wiretap channel with spatial diversity
Abstract
We experimentally demonstrate a 10 Gb/s free-space optical wiretap channel based on a spatial-diversity scheme and optical code division multiple access. In weak and middle turbulence cases, the bit error rate of a legitimate user can be decreased, and physical layer security can be simultaneously enhanced.
