Performance analysis of different modulation format on free space optical communication system

BER Evaluation of FSO Link with Hybrid Amplifier for Different Duty Cycles of RZ Pulse in Different Conditions of Rainfall

“…The performance of polarization interleaved (PI) are evaluated by using the hybrid (EDFA-Raman amplifier) amplification technique [10]. The performance comparisons of different hybrid optical amplifiers (RAMAN-EDFA, RAMAN-SOA, SOA-EDFA, and EDFA-RAMAN-EDFA) have been analysed due to varying transmission distance in between 10 to 200 km at 16 10  and 32 10  Gbps. The performance of different hybrid amplifiers is evaluated on the basis of parameter like output power, Q-factor, BER and eye opening factor.…”

“…Performance of FSO link is dependent on the modulations scheme adopted. OOK is the simple and widely adopted modulation scheme used in commercial FSO communication system because of ease in implementation, simple receiver design, bandwidth efficiency and cost effectiveness [16]. Optical carrier wave can be produced by using a LASER or LED.…”

Simulative Performance Evaluation of a Free Space Optical Communication Link Operating at 1550 nm using Different Modulation Formats

“…FSO The simulation results prove that RZ modulation format is best for long distance, but is complex and costly. Where NRZ is used for short distance and it is less complex, cheaper in comparison to RZ [13].…”

BER analysis of BPSK-SIM-based SISO and MIMO FSO systems in strong turbulence with pointing errors

“…Also, the photons transmitted by the laser are much quicker than electrons moving in a wire and they can pass straight through one another, whereas charge-bearing electrons cannot. As a result, large volumes of data can be transmitted through a confined space in FSO which is not possible to realize in other communication techniques [2].…”
