Abstract
The free-space channel is an ideal medium for communicating by means of spatially and temporally coherent optical fields. Here we derive the structure of a maximum a-posteriori optical homodyne receiver for binary antipodal signals. The effects of background radiation and phase referencing errors on receiver performance are also examined. It is shown that this receiver structure is relatively insensitive to random phase errors, while moderate background radiation has virtually no effect on receiver performance.
