In this paper, we investigated bit error rate (BER) performance of free space optical (FSO)
with On-Off Keying (OOK) modulation through maritime atmosphere channel using …

Free space optical (FSO) communication has become a research area of interest in the
domain of optical communication in recent years. However, atmospheric turbulence plays a …

Free Space Optics (FSO) is an emerging and promising communication system which
provides very high speed transmission of data, without the use of any hardware channel …

In this paper, we propose a differential on-off keying (DOOK) technique for free space optical
(FSO) communications. Intensity fluctuation caused by atmospheric turbulence is the key …

We propose a novel concatenated coding scheme combined Low Density Parity Check
(LDPC) code and vertical Bell Labs layered space-time (VBLAST) code to improve the bit …

Abstract 6G networks will provide extremely high capacity and will support a wide range of
new applications in the future, but the existing frequency bands may not be sufficient …

In the free space optical (FSO) communication system, condition of optical channel changes
continuously. In this kind of channel, a prior channel state information (CSI) at the receiver …

Free space Optical (FSO) communication systems are severely laid down with the weather
situations. Atmospheric turbulence is one of the essential facts that degrade the overall …

The use of Free Space Optical (FSO) communication systems is growing as a result of their
ability to deliver high data speeds through unlicensed spectrum with large bandwidth, higher …

Diversity combining at both transmitter and receiver end can successfully mitigate the
degradation caused by atmospheric turbulence in free space optical (FSO) links. In this …
