New Type

From several basic structures for indoor computer wireless communication system, a new type of system structure was designed. Its conformation of optics system and achievement by module were described particularly through using Fresnel lens system. This system’s link could be transformed between directed LOS link and non-directed LOS link, which made the system communicate at a high-speed when there were no barriers between the emitter and receiver and keep a good convexity when barriers appeared. At last what should be noted for the analogue simulation was brought up.

Abstract 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.
