Finite State Markov Modelling for High Speed Railway Wireless Communication Channel

Free registration required

Executive Summary

How to provide reliable, cost-effective wireless services for High-Speed Railway (HSR) users attracts increasing attention due to the fast deployment of HSRs worldwide. A key issue is to develop reasonably accurate and mathematically tractable models for HSR wireless communication channels. Finite-State Markov Chains (FSMCs) have been extensively investigated to describe wireless channels. However, different from traditional wireless communication channels, HSR communication channels have the unique features such as very high speed, deterministic mobility pattern and frequent handoff events, which are not described by the existing FSMC models.
