Modeling link quality for high speed railway wireless networks based on hidden Markov chain
... In high-speed railway (HSR) wireless networks, the link quality is greatly time-dependent and location-varying. Due to the high randomness, it is challenging to predict the link quality in HSR wireless networks. In this ...
