| Summary: | Inter-satellite optical wireless communication (IS-OWC) is one of the revolutionary
techniques that can be used to transmit the high-speed data between satellites to
accomplish space communication. However, speed and transmission distances of Is-
OWC system is limited by space turbulences particularly pointing losses at transmitter as
well as receiver side. The main intention of this thesis is to explore utilization of advance
modulation format particularly alternate mark inversion (AMI) for implementation of
high speed IS-OWC communication system with longer transmission distances which is
carried out in three phases. In the first phase, extensive literature review is completed to
find the gaps and existing techniques in IS-OWC systems. The second part covers
implementation of AMI based IS-OWC system in conjunction with polarization
interleaving (PI) scheme and wavelength division multiplexing (WDM) scheme, which
has capability to transmit 160 Gbps up-to 5000 km under no space turbulences with
acceptable signal to noise ratio (SNR), bit error rate (BER) and eye diagrams. The third
part covers the evaluation of proposed AMI-IS-OWC system under the influence of space
turbulences particularly transmitting pointing error and receiving pointing error. The
reported results show improvement in IS-OWC system as compared to previous systems
in terms of capacity as well as distance. |
