In view of the application of a visible light positioning system in a public indoor environment with numerous light emitting diodes (LEDs), a long delay is one of the main factors that limits the performance of the positioning systemwith a moving device. To solve this problem, a multiple access scheme based on block encoding time division multiplexing (TDM) is proposed in this paper. In our scheme,...
We present a Rayleigh backscattering noise mitigation scheme for 10-Gb/s loop-back WDM-PON with cascaded SOAs. OSRNR is reduced to 16.5 dB and BER is improved by 6 dB with the incorporation of microwave photonic filter.
