چکیده مقاله:
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-PPMBPSK- 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.
