A Novel Blind Spectrum Sensing Technique for Multi-User Ultraviolet Communications in Atmospheric Turbulence Channel
One of the primary challenges in multi-user free space optical wireless systems is to periodically sense the optical frequency spectrum at the receiver to identify whether the channel is occupied by other transceiver pairs in order to avoid interference. Spectrum sensing enables the user to continuo...
