FSO at Moderate Atmospheric Turbulence Using 16 QAM
For the evaluation of the system and to analyse the effect of atmospheric turbulence, a mathematical model for optical communication devices in open environment was created. The performance of the system is ve...

Performance Analysis of FSO Link in Log-Normal Channel Using Different Modulation Schemes
Free Space Optics (FSO) is an evolving branch of communication in which light signal is transmitted through free space or atmosphere which may be turbulent in nature. Due to this turbulence, the signal deterio...

Performance Comparison Between Different Dispersion Compensation Methods in an Optical Link
Dispersion is a nonlinear effect in optical fibers, which results in pulse broadening at the output of the fiber. This pulse broadening results in an increase in intersymbol interference and degrades the perfo...

SSA optimized digital pre-distorter for compensating non-linear distortion in high power amplifier
We applied the stochastic salp swarm algorithm (SSA) to design high power amplifier (PA) and digital pre-distorter (DPD) using generalized memory polynomial model. This algorithm has high exploitation and conv...

Construction of 1024-QAM Sequence as a Sum of Five QPSK Sequences with Low Peak to Average Power Ratio
Due to its high spectral efficiency, high data rate and robustness against fast fading, orthogonal frequency division multiplexing (OFDM) is widely preferred in contemporary communication systems. But OFDM suf...
