Outage Probability Analysis and Dynamic Criterion Calculation Under the Plasma Sheath Channel

Dynamic plasma sheath can lead to the communication interruption because of its severe impact on the electromagnetic waves. Existing studies mainly focused on the numerical analysis, either regarding the specific experimental results or regarding the computational modeling of the plasma sheath channel, without theoretical and quantitative analysis of the communication performance. In this paper, the bit error rate and the outage probability with m-ary frequency shift keying modulation are derived theoretically based on the hidden Markov model of plasma sheath channels. Specifically, since the outage probability can be viewed as the probability of an interruption in the communication system, it can reflect the intensity of the channel dynamics. Therefore, we analyze the effect of channel model parameters on the outage probability and propose a dynamic criterion calculation formula to model the dynamic of the plasma sheath channel. Finally, simulation results are carried out to reveal a positive correlation between the dynamic criterion and the outage probability, which shows that the dynamic criterion calculation formula can accurately illustrate the dynamic of the plasma sheath channel and the communication performance.
