For terrestrial fiber-optical data communication, the digital-coherent intradyne detection method is commonly used for data recovery at the receiver. This method has several advantages compared to optical phase locked homodyne systems. For example, the handling of phase noise is shifted into the digital domain and the fabrication of the complete system and the setup for operation are easier. Furthermore, frequency acquisition can be performed much faster, which is a major advantage in the presence of fades as in GEO space to ground links. In this paper, the demonstration of the technology in optical freespace communication is shown with the TDPI testbed.
