The signal transmission quality is not stable over a long period of time because of the polarization effects occurring along the propagation path. The Time-varying system performance (TVSP) is deduced from testbed experiments where the fluctuations of the Q-factor are measured over a prolonged period of time. From this measurement, a Gaussian distribution is fitted to the measurements in order to deduce the standard deviation (s) and the average (mean Q) of the Q-factor distribution.
