| Abstract | ||
| Optical communications that links between satellites promise to become an important element of future space infrastructure and are the subject of considerable development. A comparative performance investigation of influence of many filters in wireless communication transceivers is presented in this paper. The three filters of channel 1 have low pass Bessel filter, channel 2 has low pass Butterworth filter and channel 3 has low pass Gaussian filter are used in this research with non-return-to-zero transmission. Changeable distance from 100, 200, 300, 400 km for the different channels performed with the different values of aperture diameters varies from 10 cm to 40cm. The system , modelled and simulated by using optisystem software, in optical wireless communication Channel (OWC), is evaluated with mainly presentation signal power, delay, Q-factor and BER. It has been concluded that Low pass Bessel filter gives the best results compared with the rest of the filters. | ||
