Radiology of the Pharynx and the Esophagus is to find the random model of burst signals. This paper proposes a probability model of short burst signals based on the Poisson distribution by using the theorem of the binomial distribution to approximate the Poisson distribution, which can simulate the stochastic process of the signals entering

Unification of Multi-GNSS Bias Reference and Parameter Optimization of ISB/IFB Random Modelfect the precision orbit determination or positioning performance. In this paper, the unification method of multi-GNSS bias reference is derived, and the ISB /IFB random model is constructed based on the first-order Gaussian Markov process. The observation equation is solved by the virtual observati
