Hello,
Can someone with experience tell me what parameters can improve the BER and quality factor of RoFSO system with 0dBm,
other than using optical amplifiers and modulation techniques or raising symbol rates?
In other words, what are all the parameters that can affect the raising of the quality factor?
Thanks

      Hello Aseel,
      the Q-factor could be improved when you receive a signal with higher power and less noise. The noise could be due to different types including ISI, interference, amplifier noise, beat noise etc… The noise could be either at the transmitter, receiver or in the channel. It could be a result of dispersion or nonlinearity effects or both in the fiber. So, in summary you need to minimize the noise and improve your signal to noise ratio. You may use better detectors or coherent detection to improve the SNR.
      Regards,
      Ahmad
