Abstract
With the continuous promotion of Beidou satellite navigation applications, the pace of city market accelerate, and how to improve the navigation terminal performance is a hot issue under city environment because of its wide application and complex signal propagation. Based on received Beidou satellite signal power shadowing under different environments in city application, the paper proposed a statistical Markov model with three states: line-of-sight (LOS)-shadow-block, and using a combination of mixture Gaussian functions to approximate the distribution to describe signal variations to represent environment parameter variations. Channel parameters are evaluated from the experimental data in shanghai and utilized to verify a simulated model. Results presented in the form of signal waveforms, probability density functions show close agreement with measurements.
