Abstract: In this work, we have evaluated the bit error rate (BER) of free space optical downlink using hybrid-subcarrier-intensity-modulation (hybrid-SIM) scheme. Also, we have employed the aperture averaging technique for the improvement of its error performance.… read more here.

Abstract: The average bit error rate (ABER) performance of an avalanche-photodiode (APD)-based pulse-position modulation (PPM) free-space optical (FSO) communication system is investigated considering the aperture averaging effect. The approximate ABER expression is theoretically derived in terms… read more here.
