To improve the transceiver quality of Free Space Optical (FSO) system and ensure that user access is feasible network, a high-speed full-duplex 100 meters FSO transmission scheme using 67% duty cycle RZ-4PAM downlink alternative mark inversion (AMI) uplink signals designed system. In downlink, one PAM sequence generator Mary pulse (MPG) module are used to generate optical at 10Gbit/s through Mach-Zehnder intensity modulator (MZM). The upstream AMI by pseudo-random binary (PRBS) precoding...
In this paper, the performance of a 6GHz band visible light communication (VLC) system using dual binary (DB) downlink signals is studied. Through 7m long free space optical link, 1Gbit/s signal transmission realized in band. Using multiplier, DB mixed and modulated to frequency achieve subcarrier modulation. At same time, by changing parameters low-pass filter at receiver, transmitted compared analyzed. The simulation results show that 2.5Gbit/s rate distance 1m. No matter which used for...
