چكيده فارسي :
We report the performance of a free space
optical (FSO) communications link employing binary phase
shift keying subcarrier intensity modulation (BPSK-SIM), 4-
ary pulse position modulation (4-PPM) and hybrid 4-PPM-
BPSK-SIM, schemes in a controlled laboratory fog induced
environment. Fog is generated and controlled along a
dedicated indoor atmospheric chamber of length 6 m. We
show the advantage of employing the 4-PPM-BPSK-SIM for
FSO link over the BPSK-SIM and 4-PPM.
