A free-space optical link based on homodyne BPSK (binary phase shift keying) has been established between two of the
Canary islands, La Palma and Tenerife, to transmit 5.625 Gpbs across 142 km. This link verifies homodyne BPSK as a
robust modulation scheme even for the transmission through the atmosphere.© (2006) COPYRIGHT SPIE--The International Society for Optical Engineering. Downloading of the abstract is permitted for personal use only.
