Evaluation of inter-aircraft optical wireless communication system with different modulation formats

In this paper, simulative evaluation of the inter-aircraft optical wireless communication system with the use of different modulation formats like return to zero (RZ), non return to zero (NRZ) and raised cosine by signal to noise ratio (SNR) and quality factor (Q-factor). Performance parameters are attenuation level, transmitting pointing error and scintillation are used to analyse the performance of the system. Including the pre- and post-amplifier configuration in the system, a link range of 100 km is achieved at an acceptable bit error rate and the performance of the system is also enhanced at a 5 Gbps data rate as compared to the earlier detection mechanism.
