ABSTRACT
Aeronautical communications has advanced different solution systems that allow aircraft to maintain a link with the ground while in flight due to the growth of worldwide air traffic and the increased need for communication safety. Today, we observe that satellite solution systems are effective in supporting aeronautical communications. Indeed, satellite communications is currently playing a major role toward the implementation of a global communication infrastructure, especially given the explosive growth of wireless technology. This chapter presents the analysis and simulation of blocking and clipping probabilities for time division multiplexing (TDM) in a satellite aeronautical communications system. Specifically, we illustrate the evaluation of multiplexing systems in which the number of input sources is greater than the number of available channels. For the case of the blocking situation in synchronous TDM, we investigate the blocking probability and the average number of busy channels that can be delivered. For the case of clipping in statistical TDM, we examine the clipping probability and the expected number of busy channels that can be delivered. We compare the blocking and clipping probabilities for a fixed number of sources and different numbers of channels. We also compare the expected number of busy available channels for synchronous TDM and the average number of busy channels for statistical TDM methods for a fixed number of sources and different numbers of channels.
