Impact of Weather Conditions on Generalized Frequency Division Multiplexing over Gamma Gamma Channel

The technique called as Generalized frequency division
multiplexing (GFDM) used in the free space optical channel can be
a good option for implementation free space optical communication
systems. This technique has several strengths e.g. good spectral
efficiency, low peak-to-average power ratio (PAPR), adaptability
and low co-channel interference. In this paper, the impact of
weather conditions such as haze, rain and fog on GFDM over the
gamma-gamma channel model is discussed. A Trade off between link
distance and system performance under intense weather conditions is
also analysed. The symbol error probability (SEP) of GFDM over
the gamma-gamma turbulence channel is derived and verified with
the computer simulations.
